About this manual Its purpose The purpose of this manual is to help you get the best value from your vehicle. It can do so in several ways. It can help you decide what work must be done, even if you choose to have it done by a dealer service department or a repair shop; it provides infor¬ mation and procedures for routine mainte¬ nance and servicing; and it offers diagnostic and repair procedures to follow when trouble occurs. We hope you use the manual to tackle the work yourself. For many simpler jobs, doing it yourself may be quicker than arrang¬ ing an appointment to get the vehicle Into a shop and making the trips to leave it and pick it up. More importantly, a lot of money can be saved by avoiding the expense the shop
must pass on to you to cover its labor and overhead costs. An added benefit is the sense of satisfaction and accomplishment that you feel after doing the job yourself.
Using the manual The manual is divided into Chapters. Each Chapter is divided into numbered Sec¬ tions, which are headed in bold type between horizontal lines. Each Section consists of consecutively numbered paragraphs. At the beginning of each numbered Sec¬ tion you will be referred to any illustrations which apply to the procedures in that Sec¬ tion. The reference numbers used in illustra¬ tion captions pinpoint the pertinent Section and the Step within that Section. That is, illustration 3.2 means the illustration refers to
Section 3 and Step (or paragraph) 2 within that Section. Procedures, once described in the text, are not normally repeated. When it’s neces¬ sary to refer to another Chapter, the reference will be given as Chapter and Section number. Cross references given without use of the word “Chapter” apply to Sections and/or para¬ graphs in the same Chapter. For example, “see Section 8” means in the same Chapter. References to the left or right side of the vehicle assume you are sitting in the driver’s seat, facing forward. Even though we have prepared this manual with extreme care, neither the pub¬ lisher nor the author can accept responsibility for any errors in, or omissions from, the infor¬ mation given.
NOTE A Note provides information necessary to properly complete a procedure or information which will make the procedure easier to understand.
CAUTION A Caution provides a special procedure or special steps which must be taken while completing the procedure where the Cau¬ tion is found. Not heeding a Caution can result in damage to the assembly being worked on.
WARNING A Warning provides a special procedure or special steps which must be taken while completing the procedure where the Warning is found. Not heeding a Warning can result in personal injury.

introduction to the Chevrolet Lumina, Monte Carlo and front-wheel drive Impala The models covered by this manual are available in two and four-door sedan body styles. Engines used in these vehicles include the 3.1 and 3.4 liter OHV, 3.4 liter DOHC and a 3.8 liter (3800) V6 engine. All models are equipped with Multi-port fuel injection (MPFI). 1996 and later models are equipped with the On Board Diagnostic Second Generation (OBDII) computerized engine management system that controls virtually every aspect of engine operation. OBDII is designed to keep
the emissions system operating at the feder¬ ally specified level for the life of the vehicle. OBDII monitors emissions system compo¬ nents for signs of degradation and engine operation for any malfunction that could affect emissions, turning on the Service Engine Soon light if any faults are detected. The transversely mounted engine trans¬ mits power to the front wheels through an electronically controlled four-speed auto¬ matic transaxle via independent driveaxles. Suspension is independent in the front,
utilizing coil springs with struts and lower control arms to locate the knuckle assembly at each wheel. The rear suspension features strut/coil spring assemblies, trailing arms and lateral link rods. The rack-and-pinion steering unit is mounted behind the engine with powerassist as standard equipment. The brakes are disc at the front and disc or drums at the rear, with power assist stan¬ dard. An Anti-lock Braking System (ABS) is standard on most models.

Buying parts Replacement parts are available from many sources, which generally fall into one of two categories - authorized dealer parts departments and independent retail auto parts stores. Our advice concerning these parts is as follows: Retail auto parts stores: Good auto parts stores will stock frequently needed components which wear out relatively fast, such as clutch components, exhaust sys¬ tems, brake parts, tune-up parts, etc. These stores often supply new or reconditioned
parts on an exchange basis, which can save a considerable amount of money. Discount auto parts stores are often very good places to buy materials and parts needed for general vehicle maintenance such as oil, grease, fil¬ ters, spark plugs, belts, touch-up paint, bulbs, etc. They also usually sell tools and general accessories, have convenient hours, charge lower prices and can often be found not far from home. Authorized dealer parts department:
This is the best source for parts which
are unique to the vehicle and not generally available elsewhere (such as major engine parts, transmission parts, trim pieces, etc.). Warranty information: If the vehicle is still covered under warranty, be sure that any replacement parts purchased - regardless of the source - do not invalidate the warranty! To be sure of obtaining the correct parts, have engine and chassis numbers available and, if possible, take the old parts along for positive identification.

Maintenance techniques, tools and working facilities Maintenance techniques There are a number of techniques involved in maintenance and repair that will be referred to throughout this manual. Appli¬ cation of these techniques will enable the home mechanic to be more efficient, better organized and capable of performing the var¬ ious tasks properly, which will ensure that the repair job is thorough and complete.
Fasteners Fasteners are nuts, bolts, studs and screws used to hold two or more parts together. There are a few things to keep in mind when working with fasteners. Almost all of them use a locking device of some type, either a lockwasher, locknut, locking tab or thread adhesive. All threaded fasteners should be clean and straight, with undam¬ aged threads and undamaged corners on the hex head where the wrench fits. Develop the habit of replacing all damaged nuts and bolts with new ones. Special locknuts with nylon or fiber inserts can only be used once. If they are removed, they lose their locking ability and must be replaced with new ones. Rusted nuts and bolts should be treated with a penetrating fluid to ease removal and prevent breakage. Some mechanics use tur¬ pentine in a spout-type oil can, which works quite well. After applying the rust penetrant, let it work for a few minutes before trying to loosen the nut or bolt. Badly rusted fasteners may have to be chiseled or sawed off or removed with a special nut breaker, available at tool stores. If a bolt or stud breaks oft in an assem¬ bly, it can be drilled and removed with a spe¬ cial tool commonly available for this purpose. Most automotive machine shops can perform this task, as well as other repair procedures, such as the repair of threaded holes that have been stripped out. Flat washers and lockwashers, when removed from an assembly, should always be replaced exactly as removed. Replace any damaged washers with new ones. Never use a lockwasher on any soft metal surface (such as aluminum), thin sheet metal or plastic.
Fastener sizes For a number of reasons, automobile manufacturers are making wider and wider use of metric fasteners. Therefore, it is impor¬ tant to be able to tell the difference between standard (sometimes called U.S. or SAE) and metric hardware, since they cannot be inter¬ changed. All bolts, whether standard or metric, are sized according to diameter, thread pitch and length. For example, a standard 1/2-13x1 bolt is 1/2 inch in diameter, has 13 threads per
inch and is 1 inch long. An Ml 2 - 1.75 x 25 metric bolt is 12 mm in diameter, has a thread pitch of 1.75 mm (the distance between threads) and is 25 mm long. The two bolts are nearly identical, and easily confused, but they are not interchangeable. In addition to the differences in diame¬ ter, thread pitch and length, metric and stan¬ dard bolts can also be distinguished by examining the bolt heads. To begin with, the distance across the flats on a standard bolt head is measured in inches, while the same dimension on a metric bolt is sized in millime¬ ters (the same is true for nuts). As a result, a standard wrench should not be used on a metric bolt and a metric wrench should not be used on a standard bolt. Also, most stan¬ dard bolts have slashes radiating out from the center of the head to denote the grade or strength of the bolt, which is an indication of the amount of torque that can be applied to it. The greater the number of slashes, the
greater the strength of the bolt. Grades 0 through 5 are commonly used on automo¬ biles. Metric bolts have a property class (grade) number, rather than a slash, molded into their heads to indicate bolt strength. In this case, the higher the number, the stronger the bolt. Property class numbers 8.8, 9.8 and 10.9 are commonly used on automobiles. Strength markings can also be used to distinguish standard hex nuts from metric hex nuts. Many standard nuts have dots stamped into one side, while metric nuts are marked with a number. The greater the num¬ ber of dots, or the higher the number, the greater the strength of the nut. Metric studs are also marked on their ends according to property class (grade). Larger studs are numbered (the same as metric bolts), while smaller studs carry a geo¬ metric code to denote grade. It should be noted that many fasteners, especially Grades 0 through 2, have no dis-

Maintenance techniques, tools and working facilities tinguishing marks on them. When such is the case, the only way to determine whether it is standard or metric is to measure the thread pitch or compare it to a known fastener of the same size. Standard fasteners are often referred to as SAE, as opposed to metric. However, it should be noted that SAE technically refers to a non-metric fine thread fastener only. Coarse thread non-metric fasteners are referred to as USS sizes. Since fasteners of the same size (both standard and metric) may have different strength ratings, be sure to reinstall any bolts, studs or nuts removed from your vehicle in their original locations. Also, when replacing a fastener with a new one, make sure that the new one has a strength rating equal to or greater than the original.
D
Most threaded fasteners should be tightened to a specific torque value (torque is the twisting force applied to a threaded com¬ ponent such as a nut or bolt). Overtightening the fastener can weaken it and cause it to break, while undertightening can cause it to eventually come loose. Bolts, screws and studs, depending on the material they are made of and their thread diameters, have specific torque values, many of which are noted in the Specifications at the beginning of each Chapter. Be sure to follow the torque recommendations closely. For fasteners not assigned a specific torque, a general torque value chart is presented here as a guide. These torque values are for dry (unlubricated)

fasteners threaded into steel or cast iron (not aluminum). As was previously mentioned, the size and grade of a fastener determine the amount of torque that can safely be applied to it. The figures listed here are approximate for Grade 2 and Grade 3 fasteners. Higher grades can tolerate higher torque values. Fasteners laid out in a pattern, such as cylinder head bolts, oil pan bolts, differential cover bolts, etc., must be loosened or tight¬ ened in sequence to avoid warping the com¬ ponent. This sequence will normally be shown in the appropriate Chapter. If a spe¬ cific pattern is not given, the following proce¬ dures can be used to prevent warping. Initially, the bolts or nuts should be assembled finger-tight only. Next, they should be tightened one full turn each, in a criss-cross or diagonal pattern. After each one has been tightened one full turn, return to the first one and tighten them all one-half turn, following the same pattern. Finally, tighten each of them one-quarter turn at a time until each fastener has been tightened to the proper torque. To loosen and remove the fasteners, the procedure would be reversed.
Component disassembly Component disassembly should be done with care and purpose to help ensure that the parts go back together properly. Always keep track of the sequence in which parts are removed. Make note of special characteristics or marks on parts that can be installed more than one way, such as a grooved thrust washer on a shaft. It is a good idea to lay the disassembled parts out on a clean surface in the order that they were removed. It may also be helpful to make sketches or take instant photos of compo¬ nents before removal. When removing fasteners from a com¬ ponent, keep track of their locations. Some¬ times threading a bolt back in a part, or putting the washers and nut back on a stud, can prevent mix-ups later. If nuts and bolts cannot be returned to their original locations, they should be kept in a compartmented box or a series of small boxes. A cupcake or muf¬ fin tin is ideal for this purpose, since each cavity can hold the bolts and nuts from a par¬ ticular area (i.e. oil pan bolts, valve cover bolts, engine mount bolts, etc.). A pan of this type is especially helpful when working on assemblies with very small parts, such as the carburetor, alternator, valve train or interior dash and trim pieces. The cavities can be marked with paint or tape to identify the con¬ tents. Whenever wiring looms, harnesses or connectors are separated, it is a good idea to identify the two halves with numbered pieces of masking tape so they can be easily recon¬ nected.
Gasket sealing surfaces Throughout any vehicle, gaskets are used to seal the mating surfaces between two parts and keep lubricants, fluids, vacuum or pressure contained in an assembly.
0-8
Maintenance techniques, tools and working facilities
Micrometer set Many times these gaskets are coated with a liquid or paste-type gasket sealing compound before assembly. Age, heat and pressure can sometimes cause the two parts to stick together so tightly that they are very difficult to separate. Often, the assembly can be loosened by striking it with a soft-face hammer near the mating surfaces. A regular hammer can be used If a block of wood is placed between the hammer and the part. Do not hammer on cast parts or parts that could be easily damaged. With any particularly stubborn part, always recheck to make sure that every fastener has been removed. Avoid using a screwdriver or bar to pry apart an assembly, as they can easily mar the gasket sealing surfaces of the parts, which must remain smooth. If prying Is absolutely necessary, use an old broom handle, but keep In mind that extra clean up will be nec¬ essary if the wood splinters. After the parts are separated, the old gasket must be carefully scraped off and the gasket surfaces cleaned. Stubborn gasket material can be soaked with rust penetrant or treated with a special chemical to soften it so it can be easily scraped off. A scraper can be fashioned from a piece of copper tubing by flattening and sharpening one end. Copper is recommended because it is usually softer than the surfaces to be scraped, which reduces the chance of gouging the part. Some gaskets can be removed with a wire brush, but regardless of the method used, the mating surfaces must be left clean and smooth. If for some reason the gasket sur¬ face is gouged, then a gasket sealer thick enough to fill scratches will have to be used during reassembly of the components. For most applications, a non-drying (or semi-dry¬ ing) gasket sealer should be used.
Hose removal tips Warning: If the vehicle is equipped with air conditioning, do not disconnect any of the A/C hoses without first having the system depressurized by a dealer service department or a service station. Hose removal precautions closely paral¬ lel gasket removal precautions. Avoid scratching or gouging the surface that the hose mates against or the connection may
Dial indicator set leak. This is especially true for radiator hoses. Because of various chemical reactions, the rubber in hoses can bond itself to the metal spigot that the hose fits over. To remove a hose, first loosen the hose clamps that secure it to the spigot. Then, with slip-joint pliers, grab the hose at the clamp and rotate it around the spigot. Work it back and forth until it is completely free, then pull it off. Sili¬ cone or other lubricants will ease removal if they can be applied between the hose and the outside of the spigot. Apply the same lubricant to the inside of the hose and the outside of the spigot to simplify installation. As a last resort (and if the hose is to be replaced with a new one anyway), the rubber can be slit with a knife and the hose peeled from the spigot. If this must be done, be careful that the metal connection is not dam¬ aged. If a hose clamp is broken or damaged, do not reuse it. Wire-type clamps usually weaken with age, so it is a good idea to replace them with screw-type clamps when¬ ever a hose is removed.
Tools A selection of good tools is a basic requirement for anyone who plans to main¬ tain and repair his or her own vehicle. For the owner who has few tools, the initial invest¬ ment might seem high, but when compared to the spiraling costs of professional auto maintenance and repair, it is a wise one. To help the owner decide which tools are needed to perform the tasks detailed in this manual, the following tool lists are offered: Maintenance and minor repair, Repair/overhaul and Special. The newcomer to practical mechanics should start off with the maintenance and minor repair tool kit, which is adequate for the simpler jobs performed on a vehicle. Then, as confidence and experience grow, the owner can tackle more difficult tasks, buying additional tools as they are needed. Eventually the basic kit will be expanded into the repair and overhaul tool set. Over a period of time, the experienced do-it-yourselfer will assemble a tool set complete enough for most repair and overhaul procedures and will add tools from the special category when it is
felt that the expense is justified by the fre¬ quency of use.
Maintenance and minor repair tool kit The tools in this list should be consid¬ ered the minimum required for performance of routine maintenance, servicing and minor repair work. We recommend the purchase of combination wrenches (box-end and openend combined in one wrench). While more expensive than open end wrenches, they offer the advantages of bofh fypes of wrench. Combination wrench set (1/4-inch to 1 inch or 6 mm to 19 mm) Adjustable wrench, 8 inch Spark plug wrench with rubber insert Spark plug gap adjusting tool Feeler gauge set Brake bleeder wrench Standard screwdriver (5/16-inch x 6 inch) Phillips screwdriver (No. 2x6 inch) Combination pliers - 6 inch Hacksaw and assortment of blades Tire pressure gauge Grease gun Oil can Fine emery cloth Wire brush Battery post and cable cleaning tool Oil filter wrench Funnel (medium size) Safety goggles Jackstands (2) Drain pan Note: If basic tune-ups are going to be part of routine maintenance, it will be necessary to purchase a good quality stroboscopic timing light and combination tachometer/dwell meter. Although they are included in the list of special tools, it is mentioned here because they are absolutely necessary for tuning most vehicles properly.
Repair and overhaul tool set These tools are essential for anyone who plans to perform major repairs and are in addition to those in the maintenance and minor repair tool kit. Included is a compre¬ hensive set of sockets which, though expen¬ sive, are invaluable because of their versatil-

Special tools The tools in this list include those which are not used regularly, are expensive to buy, or which need to be used in accordance with their manufacturer’s instructions. Unless these tools will be used frequently, it is not very economical to purchase many of them. A consideration would be to split the cost and use between yourself and a friend or friends. In addition, most of these tools can be obtained from a tool rental shop on a tem¬ porary basis. This list primarily contains only those tools and instruments widely available to the public, and not those special tools produced by the vehicle manufacturer for distribution to dealer service departments. Occasionally, references to the manufacturer’s special tools are included in the text of this manual. Generally, an alternative method of doing the job without the special tool is offered. How¬ ever, sometimes there is no alternative to their use. Where this is the case, and the tool cannot be purchased or borrowed, the work should be turned over to the dealer service department or an automotive repair shop.

Buying tools For the do-it-yourselfer who is just start¬ ing to get involved in vehicle maintenance and repair, there are a number of options available when purchasing tools. If mainte¬ nance and minor repair is the extent of the work to be done, the purchase of individual tools is satisfactory. If, on the other hand, extensive work is planned, it would be a good idea to purchase a modest tool set from one of the large retail chain stores. A set can usu¬ ally be bought at a substantial savings over the individual tool prices, and they often come with a tool box. As additional tools are needed, add-on sets, individual tools and a larger tool box can be purchased to expand
Maintenance techniques, tools and working facilities the tool selection. Building a tool set gradu¬ ally allows the cost of the tools to be spread over a longer period of time and gives the mechanic the freedom to choose only those tools that will actually be used. Tool stores will often be the only source of some of the special tools that are needed, but regardless of where tools are bought, try to avoid cheap ones, especially when buying screwdrivers and sockets, because they won’t last very long. The expense involved in replacing cheap tools will eventually be greater than the initial cost of quality tools.
Care and maintenance of tools Good tools are expensive, so it makes sense to treat them with respect. Keep them clean and in usable condition and store them properly when not in use. Always wipe off any dirt, grease or metal chips before putting them away. Never leave tools lying around in the work area. Upon completion of a job, always check closely under the hood for tools that may have been left there so they won’t get lost during a test drive. Some tools, such as screwdrivers, pli¬ ers, wrenches and sockets, can be hung on a panel mounted on the garage or workshop wall, while others should be kept in a tool box or tray. Measuring instruments, gauges, meters, etc, must be carefully stored where they cannot be damaged by weather or impact from other tools. When tools are used with care and stored properly, they will last a very long time. Even with the best of care, though, tools will wear out if used frequently. When a tool is damaged or worn out, replace it. Sub¬ sequent jobs will be safer and more enjoyable if you do.
How to repair damaged threads Sometimes, the internal threads of a nut
or bolt hole can become stripped, usually from overtightening. Stripping threads is an all-too-common occurrence, especially when working with aluminum parts, because alu¬ minum is so soft that it easily strips out. Usually, external or internal threads are only partially stripped. After they’ve been cleaned up with a tap or die, they’ll still work. Sometimes, however, threads are badly dam¬ aged. When this happens, you’ve got three choices: 1) Drill and tap the hole to the next suitable oversize and install a larger diameter bolt, screw or stud. 2) Drill and tap the hole to accept a threaded plug, then drill and tap the plug to the original screw size. You can also buy a plug already threaded to the origi¬ nal size. Then you simply drill a hole to the specified size, then run the threaded plug into the hole with a bolt and jam nut. Once the plug is fully seated, remove the jam nut and bolt. 3) The third method uses a patented thread repair kit like Heli-Coil or Slimsert. These easy-to-use kits are designed to repair damaged threads in straightthrough holes and blind holes. Both are available as kits which can handle a vari¬ ety of sizes and thread patterns. Drill the hole, then tap It with the special included tap. Install the Hell-Coil and the hole is back to its original diameter and thread pitch. Regardless of which method you use, be sure to proceed calmly and carefully. A lit¬ tle impatience or carelessness during one of these relatively simple procedures can ruin your whole day’s work and cost you a bundle if you wreck an expensive part.
Working facilities Not to be overlooked when discussing tools is the workshop. If anything more than
0-11
routine maintenance is to be carried out, some sort of suitable work area is essential. It is understood, and appreciated, that many home mechanics do not have a good workshop or garage available, and end up removing an engine or doing major repairs outside. It is recommended, hovyever, that the overhaul or repair be completed under the cover of a roof. A clean, flat workbench or table of com¬ fortable working height is an absolute neces¬ sity. The workbench should be equipped with a vise that has a jaw opening of at least four inches. As mentioned previously, some clean, dry storage space is also required for tools, as well as the lubricants, fluids, cleaning sol¬ vents, etc. which soon become necessary. Sometimes waste oil and fluids, drained from the engine or cooling system during nor¬ mal maintenance or repairs, present a dis¬ posal problem. To avoid pouring them on the ground or into a sewage system, pour the used fluids into large containers, seal them with caps and take them to an authorized disposal site or recycling center. Plastic jugs, such as old antifreeze containers, are ideal for this purpose. Always keep a supply of old newspa¬ pers and clean rags available. Old towels are excellent for mopping up spills. Many mechanics use rolls of paper towels for most work because they are readily available and disposable. To help keep the area under the vehicle clean, a large cardboard box can be cut open and flattened to protect the garage or shop floor. Whenever working over a painted sur¬ face, such as when leaning over a fender to service something under the hood, always cover it with an old blanket or bedspread to protect the finish. Vinyl covered pads, made especially for this purpose, are available at auto parts stores.
Anti-theft audio system General information 1 Some of these models are equipped with THEFTLOCK audio systems, which include an anti-theft feature that will render the stereo inoperative if stolen. If the power source to the stereo is cut with the anti-theft feature activated, the stereo will be inopera¬ tive. Even if the power source is immediately re-connected, the stereo will not function. 2 If your vehicle is equipped with this anti¬ theft system, do not disconnect the battery, remove the stereo or disconnect related components unless you have either turned off the feature or have the individual ID (code) number for the stereo.
Disabling the anti-theft feature 3
Press the stereo’s 1 and 4 buttons at the
same time for five seconds with the ignition on and the radio power off. The display will show SEC, indicating the unit is in the secure mode (anti-theft feature enabled). 4 Press the MIN button. The display will show “000”. 5 Press the MIN button to make the last two numbers appear. 6 Press HR to display the first one or two numbers of your code. The numbers will be displayed as entered. 7 Press AM/FM. If the display shows you have successfully disabled the anti-theft feature. If SEC is displayed, the code you entered was incorrect and the anti-theft fea¬ ture is still enabled.
Unlocking the stereo after a power loss 8 When power is restored to the stereo, the stereo won’t turn on and LOG will appear on the display. Enter your ID code as follows; pause no more than 15 seconds between Steps. 9 Turn the ignition switch to ON, but leave the stereo off. 10 Press the MIN button. “000” should dis¬ play. 11 Press the HR button to make the last two numbers appear, then release the button. 12 Press the HR button until the first one or two numbers appear. 13 Press AM/FM. SEC should appear, indi¬ cating the stereo is unlocked. If LOG appears, the numbers you entered were not correct and the stereo is still inoperative.

Jacking and towing Jacking Warning: The Jack supplied with the vehicle should only be used for raising the vehicle when changing a tire or placing jackstands under the frame. Never work under the vehi¬ cle or start the engine while the jack is being used as the only means of support. The vehicle must be on a level surface with the wheels blocked and the transmission in Park. Apply the parking brake if the front of the vehicle must be raised. Make sure no one is in the vehicle as it’s being raised with the jack.
The head of the jack should fit squarely in the notch on the rocker flange at either the front or rear of the vehicle
Remove the jack, lug nut wrench and spare'tire from the trunk compartment. To replace the tire, use the tapered end of the lug wrench to pry loose the wheel cover. Note: If the vehicle is equipped with aluminum wheels, it may be necessary to pry out the special lug nut covers. Also, aluminum wheels normally have anti-theft lug nuts (one per wheel) which require using a special “key" between the lug wrench and lug nut. The key is usually in the glove compartment. Loosen the lug nuts one-half turn, but leave them in place until the tire is raised off the ground. Position the jack under the side of the vehicle at the indicated jacking points. There’s a front and rear jacking point on each side of the vehicle (see illustration). Turn the jack handle clockwise (the lug wrench also serves as the jack handle) until the tire clears the ground. Remove the lug nuts and pull the tire off. Clean the mating surfaces of the hub and wheel, then install the spare. Replace the lug nuts with the beveled edges facing in and tighten them snugly. Don’t attempt to tighten them com¬ pletely until the vehicle is lowered or it could slip off the jack. Turn the jack handle counterclockwise to lower the vehicle. Remove the jack and tighten the lug nuts in a criss-cross pattern. If possible, tighten the nuts with a torque wrench (see Chapter 1 for the torque values). If you don’t have access to a torque wrench.
have the nuts checked by a service station or repair shop as soon as possible. Caution: The compact spare included with these vehi¬ cles is intended for temporary use only. Have the tire repaired and reinstall it on the vehicle at the earliest opportunity and don’t exceed 50 mph with the spare tire on the car. Install the wheel cover, then stow the tire, jack and wrench and unblock the wheels.
Towing We recommend these vehicles be towed from the front, with the front wheels off the ground. If it’s absolutely necessary, these vehicles can be towed from the rear with the front wheels on the ground, provided that speeds don’t exceed 35 mph and the dis¬ tance is less than 50 miles; the transaxle can be damaged if these mileage/speed limita¬ tions are exceeded. Equipment specifically designed for towing should be used. It must be attached to the main structural members of the vehi¬ cle, not the bumpers or brackets. Safety is a major consideration when towing and all applicable state and local laws must be obeyed. A safety chain must be used at all times. The parking brake must be released and the transaxie must be in Neutral. The steering must be unlocked (ignition switch in the Off position). Remember that power steering and power brakes won’t work with the engine off.
Booster battery Gump) starting Observe these precautions when using a booster battery to start a vehicle: a) Before connecting the booster battery, make sure the ignition switch is in the Off position. b) Turn off the lights, heater and other electrical loads. c) Your eyes should be shielded. Safety goggles are a good idea. d) Make sure the booster battery is the same voltage as the dead one in the vehicle. e) The two vehicles MUST NOT TOUOH each other! f) Make sure the transaxle is in Neutral (manual) or Park (automatic). g) If the booster battery is not a mainte¬ nance-free type, remove the vent caps and lay a cloth over the vent holes. Connect the red jumper cable to the positive (+) terminals of each battery. Note: The vehicles covered in this manual are equipped with a remote positive terminal. This terminal is located in the left (driver’s) side of the engine compartment, covered by a red plastic cap (see illustration). Connect one end of the black jumper cable to the negative (-) terminal of the
booster battery. The other end of this cable should be connected to a good ground on the vehicle to be started, such as a bolt or bracket on the body. Remote positive
Start the engine using the booster bat¬ tery, then, with the engine running at idle speed, disconnect the jumper cables in the reverse order of connection. Make the booster battery

Automotive chemicals and lubricants A number of automotive chemicals and lubricants are available for use during vehicle maintenance and repair. They include a wide variety of products ranging from cleaning sol¬ vents and degreasers to lubricants and protective sprays for rubber, plastic and vinyl.
Carburetor cleaner and choke cleaner is a strong solvent for gum, varnish and car¬ bon. Most carburetor cleaners leave a drytype lubricant film which will not harden or gum up. Because of this film it is not recommended for use on electrical compo¬ nents. Brake system cleaner is used to remove grease and brake fluid from the brake system, where clean surfaces are absolutely necessary. It leaves no residue and often eliminates brake squeal caused by contami¬ nants. Electrical cleaner removes oxidation, corrosion and carbon deposits from electrical contacts, restoring full current flow. It can also be used to clean spark plugs, carburetor jets, voltage regulators and other parts where an oil-free surface is desired. Demoisturants remove water and mois¬ ture from electrical components such as alter¬ nators, voltage regulators, electrical connec¬ tors and fuse blocks. They are non-conductive, non-corrosive and non-flammable. Degreasers are heavy-duty solvents used to remove grease from the outside of the engine and from chassis components. They can be sprayed or brushed on and, depend¬ ing on the type, are rinsed off either with water or solvent.
High-temperature wheel bearing grease is designed to withstand the extreme temperatures encountered by wheel bearings in disc brake equipped vehicles. It usually contains molybdenum disulfide (moly), which is a dry-type lubricant. White grease is a heavy grease for metal-to-metal applications where water is a problem. White grease stays soft under both low and high temperatures (usually from -100 to +190-degrees F), and will not wash off or dilute in the presence of water. Assembly lube is a special extreme pressure lubricant, usually containing moly, used to lubricate high-load parts (such as main and rod bearings and cam lobes) for initial start-up of a new engine. The assembly lube lubricates the parts without being squeezed out or washed away until the engine oiling system begins to function. Silicone lubricants are used to protect rubber, plastic, vinyl and nylon parts. Graphite lubricants are used where oils cannot be used due to contamination prob¬ lems, such as in locks. The dry graphite will lubricate metal parts while remaining uncon¬ taminated by dirt, water, oil or acids. It is electrically conductive and will not foul elec¬ trical contacts in locks such as the ignition switch. Moly penetrants loosen and lubricate frozen, rusted and corroded fasteners and prevent future rusting or freezing. Heat-sink grease is a special electri¬ cally non-conductive grease that is used for mounting electronic ignition modules where it is essential that heat is transferred away from the module.
Lubricants
Sealants
Motor oil is the lubricant formulated for use in engines. It normally contains a wide variety of additives to prevent corrosion and reduce foaming and wear. Motor oil comes in various weights (viscosity ratings) from 0 to 50. The recommended weight of the oil depends on the season, temperature and the demands on the engine. Light oil is used in cold climates and under light load conditions. Heavy oil is used in hot climates and where high loads are encountered. Multi¬ viscosity oils are designed to have character¬ istics of both light and heavy oils and are available in a number of weights from 5W-20 to 20W-50. Gear oil is designed to be used in differ¬ entials, manual transmissions and other areas where high-temperature lubrication is required. Chassis and wheel bearing grease is a heavy grease used where increased loads and friction are encountered, such as for wheel bearings, balljoints, tie-rod ends and universal joints.
RTV seaiant is one of the most widely used gasket compounds. Made from sili¬ cone, RTV is air curing, it seals, bonds, waterproofs, fills surface irregularities, remains flexible, doesn’t shrink, is relatively easy to remove, and is used as a supplemen¬ tary sealer with almost all low and medium temperature gaskets. Anaerobic sealant is much like RTV in that it can be used either to seal gaskets or to form gaskets by itself. It remains flexible, is solvent resistant and fills surface imperfec¬ tions. The difference between an anaerobic sealant and an RTV-type sealant is in the cur¬ ing. RTV cures when exposed to air, while an anaerobic sealant cures only in the absence of air. This means that an anaerobic sealant cures only after the assembly of parts, seal¬ ing them together. Thread and pipe sealant is used for sealing hydraulic and pneumatic fittings and vacuum lines. It is usually made from a Teflon compound, and comes in a spray, a paint-on liquid and as a wrap-around tape.
Cleaners
Chemicals Anti-seize compound prevents seizing, galling, cold welding, rust and corrosion in fasteners. High-temperature ant-seize, usu¬ ally made with copper and graphite lubri¬ cants, is used for exhaust system and exhaust manifold bolts. Anaerobic locking compounds are used to keep fasteners from vibrating or working loose and cure only after installation, in the absence of air. Medium strength lock¬ ing compound is used for small nuts, bolts and screws that may be removed later. Highstrength locking compound is for large nuts, bolts and studs which aren’t removed on a regular basis. OH additives range from viscosity index improvers to chemical treatments that claim to reduce internal engine friction. It should be noted that most oil manufacturers caution against using additives with their oils. Gas additives perform several func¬ tions, depending on their chemical makeup. They usually contain solvents that help dis¬ solve gum and varnish that build up on car¬ buretor, fuel injection and intake parts. They also serve to break down carbon deposits that form on the inside surfaces of the com¬ bustion chambers. Some additives contain upper cylinder lubricants for valves and pis¬ ton rings, and others contain chemicals to remove condensation from the gas tank.
Miscellaneous Brake fluid is specially formulated hydraulic fluid'that can withstand the heat and pressure encountered in brake systems. Care must be taken so this fluid does not come in contact with painted surfaces or plastics. An opened container should always be resealed to prevent contamination by water or dirt. Weatherstrip adhesive is used to bond weatherstripping around doors, windows and trunk lids. It is sometimes used to attach trim pieces. Undercoating is a petroleum-based, tar-like substance that is designed to protect metal surfaces on the underside of the vehi¬ cle from corrosion. It also acts as a sounddeadening agent by insulating the bottom of the vehicle. Waxes and polishes are used to help protect painted and plated surfaces from the weather. Different types of paint may require the use of different types of wax and polish. Some polishes utilize a chemical or abrasive cleaner to help remove the top layer of oxi¬ dized (dull) paint on older vehicles. In recent years many non-wax polishes that contain a wide variety of chemicals such as polymers and silicones have been introduced. These non-wax polishes are usually easier to apply and last longer than conventional waxes and polishes.

Safety first! Regardless of how enthusiastic you may be about getting on with the job at hand, take the time to ensure that your safety is not jeopardized. A moment’s lack of attention can result in an accident, as can failure to observe certain simple safety precautions. The possibility of an accident will always exist, and the following points should not be considered a comprehensive list of all dan¬ gers. Rather, they are intended to make you aware of the risks and to encourage a safety conscious approach to all work you carry out on your vehicle.
Essential DOs and DON’Ts DON’T rely on a jack when working under the vehicle. Always use approved jackstands to support the weight of the vehicle and place them under the recommended lift or support points. DON’T attempt to loosen extremely tight fas¬ teners (i.e. wheel lug nuts) while the vehicle is on a jack - it may fall. DON’T start the engine without first making sure that the transmission is in Neutral (or Park where applicable) and the parking brake is set. DON’T remove the radiator cap from a hot cooling system - let it cool or cover it with a cloth and release the pressure gradually. DON’T attempt to drain the engine oil until you are sure it has cooled to the point that it will not burn you. DON’T touch any part of the engine or ex¬ haust system until it has cooled sufficiently to avoid burns. DON’T siphon toxic liquids such as gasoline, antifreeze and brake fluid by mouth, or allow them to remain on your skin. DON’T inhale brake lining dust - it is poten¬ tially hazardous (see Asbestos below). DON’T allow spilled oil or grease to remain on the floor - wipe it up before someone slips on it. DON’T use loose fitting wrenches or other tools which may slip and cause injury. DON’T push on wrenches when loosening or tightening nuts or bolts. Always try to pull the wrench toward you. If the situation calls for pushing the wrench away, push with an open hand to avoid scraped knuckles if the wrench should slip. DON’T attempt to lift a heavy component alone - get someone to help you. DON’T rush or take unsafe shortcuts to finish a job. DON’T allow children or animals in or around the vehicle while you are working on it. DO wear eye protection when using
power tools such as a drill, sander, bench grinder, etc. and when working under a vehi¬ cle. DO keep loose clothing and long hair well out of the way of moving parts. DO make sure that any hoist used has a safe working load rating adequate for the job. DO get someone to check on you periodically when working alone on a vehicle. DO carry out work in a logical sequence and make sure that everything is correctly assem¬ bled and tightened. DO keep chemicals and fluids tightly capped and out of the reach of children and pets. DO remember that your vehicle’s safety affects that of yourself and others. If in doubt on any point, get professional advice.
Asbestos Certain friction, insulating, sealing, and other products - such as brake linings, brake bands, clutch linings, torque converters, gas¬ kets, etc. - may contain asbestos. Extreme care must be taken to avoid inhalation of dust from such products, since it is hazardous to health. If in doubt, assume that they do con¬ tain asbestos.
Fire Remember at all times that gasoline is highly flammable. Never smoke or have any kind of open flame around when working on a vehicle. But the risk does not end there. A spark caused by an electrical short circuit, by two metal surfaces contacting each other, or even by static electricity built up in your body under certain conditions, can ignite gasoline vapors, which in a confined space are highly explosive. Do not, under any circumstances, use gasoline for cleaning parts. Use an approved safety solvent. Always disconnect the battery ground (-) cable at the battery before working on any part of the fuel system or electrical system. Never risk spilling fuel on a hot engine or exhaust component. It is strongly recom¬ mended that a fire extinguisher suitable for use on fuel and electrical fires be kept handy in the garage or workshop at all times. Never try to extinguish a fuel or electrical fire with water.
Fumes Certain fumes are highly toxic and can quickly cause unconsciousness and even death if inhaled to any extent. Gasoline vapor falls into this category, as do the vapors from some cleaning solvents. Any draining or pouring of such volatile fluids should be done in a well ventilated area.
When using cleaning fluids and sol¬ vents, read the instructions on the container carefully. Never use materials from unmarked containers. Never run the engine in an enclosed space, such as a garage. Exhaust fumes con¬ tain carbon monoxide, which is extremely poisonous. If you need to run the engine, always do so in the open air, or at least have the rear of the vehicle outside the work area. If you are fortunate enough to have the use of an inspection pit, never drain or pour gasoline and never run the engine while the vehicle is over the pit. The fumes, being heavier than air, will concentrate in the pit with possibly lethal results.
The battery Never create a spark or allow a bare light bulb near a battery. They normally give off a certain amount of hydrogen gas, which is highly explosive. Always disconnect the battery ground (-) cable at the battery before working on the fuel or electrical systems. If possible, loosen the filler caps or cover when charging the battery from an external source (this does not apply to sealed or maintenance-free batteries). Do not charge at an excessive rate or the battery may burst. Take care when adding water to a non maintenance-free battery and when carrying a battery. The electrolyte, even when diluted, is very corrosive and should not be allowed to contact clothing or skin. Always wear eye protection when clean¬ ing the battery to prevent the caustic deposits from entering your eyes.
Household current When using an electric power tool, inspection light, etc., which operates on household current, always make sure that the tool is correctly connected to its plug and that, where necessary, it is properly grounded. Do not use such items in damp conditions and, again, do not create a spark or apply excessive heat in the vicinity of fuel or fuel vapor.
Secondary ignition system voltage A severe electric shock can result from touching certain parts of the ignition system (such as the spark plug wires) when the engine is running or being cranked, particu¬ larly if components are damp or the insulation is defective. In the case of an electronic igni¬ tion system, the secondary system voltage is much higher and could prove fatal.

26 Miscellaneous engine noises 1 A strong dull noise that becomes more rapid as the engine accelerates indicates worn or damaged crankshaft bearings or an unevenly worn crankshaft. To pinpoint the trouble spot, remove the spark plug wire from one plug at a time and crank the engine over. If the noise stops, the cylinder with the removed plug wire indicates the problem area. Replace the bearing and/or service or replace the crankshaft (Chapter 2). 2 A similar (yet slightly higher pitched) noise to the crankshaft knocking described in the previous paragraph, that becomes more rapid as the engine accelerates, indicates worn or damaged connecting rod bearings (Chapter 2). The procedure for locating the problem cylinder is the same as described in Paragraph 1. 3 An overlapping metallic noise that increases in intensity as the engine speed increases, yet diminishes as the engine warms up indicates abnormal piston and cylinder wear (Chapter 2).To locate the prob¬ lem cylinder, use the procedure described in Paragraph 1. 4 A rapid clicking noise that becomes
faster as the engine accelerates indicates a worn piston pin or piston pin hole. This sound will happen each time the piston hits the highest and lowest points in the stroke (Chapter 2). The procedure for locating the problem piston is described in Para¬ graph 1. 5 A metallic clicking noise coming from the water pump indicates worn or damaged water pump bearings or pump. Replace the water pump with a new one (Chapter 3). 6 A rapid tapping sound or clicking sound that becomes faster as the engine speed increases indicates “valve tapping” or stuck valve lifters. This can be identified by holding one end of a section of hose to your ear and placing the other end at different spots along the rocker arm cover. The point where the sound is loudest indicates the problem valve. Adjust the valve clearance (Chapter 1). 7 A steady metallic rattling or rapping sound coming from the area of the timing chain cover indicates a worn, damaged or out-of-adjustment timing chain. Service or replace the chain and related components (Chapter 2).
27 Overheating 1 Insufficient coolant in system (Chap¬ ter 1). 2 Water pump drivebelt defective or out of adjustment (Chapter 1). 3 Radiator core blocked or grille restricted (Chapter 3). 4 Thermostat faulty (Chapter 3). 5 Electric cooling fan blades broken or cracked (Chapter 3). 6 Radiator cap not maintaining proper pressure (Chapter 3).

32 Poor coolant circulation 1 Inoperative water pump (Chapter 3). 2 Restriction in cooling system (Chap¬ ters 1 and 3). 3 Water pump drivebelt defective or out of adjustment (Chapter 1). 4 Thermostat sticking (Chapter 3).
Automatic transaxle Note: Due to the complexity of the automatic transaxle, it’s difficult for the home mechanic to properly diagnose and service this compo¬ nent. For problems other than the following, the vehicle should be taken to a dealer ser¬ vice department or a transmission shop.
33 Fluid leakage 1 Automatic transmission fluid is a deep red color. Fluid leaks should not be confused with engine oil, which can easily be blown by air flow to the transaxle. 2 To pinpoint a leak, first remove all builtup dirt and grime from the transaxle housing with degreasing agents and/or steam clean¬ ing. Drive the vehicle at low speeds so air flow will not blow the leak far from its source. Raise the vehicle and determine where the leak is coming from. Common areas of leakage are: a) Pan (Chapters 1 and 7) b) Fiiler pipe (Chapter 7) c) Transaxle oil lines (Chapter 7) d) Speedometer gear or sensor (Chapter 7) e) Vacuum modulator (Chapter 7)
Faulty thermostat (Chapter 3).
29 External coolant leakage 1 Deteriorated/damaged hoses or loose clamps (Chapters 1 and 3). 2 Water pump seal defective (Chapters 1 and 3). 3 Leakage from radiator core or header tank (Chapter 3). 4 Engine drain or water jacket core plugs leaking (Chapter 2). 5 Leak at engine oil cooler (Chapter 3).
30 Internal coolant leakage 1 Leaking cylinder head gasket (Chap¬ ter 2). 2 Cracked cylinder bore or cylinder head (Chapter 2).
34 Transaxle fluid brown or has a burned smell Transaxle overheated. Change the fluid (Chapter 1).
35 General shift mechanism problems 1 Chapter 7 deals with checking and adjusting the shift linkage on automatic transaxles. Common problems which may be attributed to poorly adjusted linkage are: a) Engine starting in gears other than Park or Neutral. b) Indicator on shifter pointing to a gear other than the one actually being used. c) Vehicle moves when in Park. 2 Refer to Chapter 7 for the shift linkage adjustment procedure.

38 Transaxle slips, shifts roughly, is noisy or has no drive in forward or reverse gears There are many probable causes for the above problems, but the home mechanic should be concerned with only one possibility - fluid level. Before taking the vehicle to a repair shop, check the level and condition of the fluid as described in Chapter 1. Correct the fluid level as necessary or change the fluid and filter if needed. If the problem persists, have a professional diag¬ nose the probable cause.

General information
Refer to illustrations 1.1a, 1.1b and 1.2 Warning: Whenever any of the suspension or steering fasteners are loosened or removed, they must be inspected and, if necessary, replaced with new ones of the same part number or of original equipment quality and design. Torque specifications must be followed for proper reassembly and component retention. Never attempt to heat or straighten any suspension or steering components. Instead, replace any bent or damaged part with a new one. The front suspension on Lumina and 1999 and earlier Monte Carlo models is a strut design that is made up of a strut weided to a knuckie and supported by a coii spring. The strut/knuckle bearing is located under the lower spring seat, with the upper spring seat attaching to the chassis. Because of the iocation of the bearing on the Lumina and 1999 and eariier Monte Carlo models, the strut cartridge can be removed from the engine compartment without disassembiing the spring and strut/knuckle. On 2000 and iater modei Monte Cario and Impaia models, strut replacement requires disassembiy of the spring and strut/knuckie assembiy. The strut/ knuckie assembiies are connected by balijoints to the iower controi arms, which are mounted to the frame. The control arms are connected by a stabilizer bar, which reduces body lean during cornering (see illustrations). The rear suspension is independent, with a coii spring/strut assembiy on each side bolted to knuckle assemblies that are located by trailing arms, paraiiei iateral iinks, and a stabilizer bar (see illustration). The rack-and-pinion steering gear is located behind the engine/transaxie assembiy on the subframe and actuates the steering arms that connect to the steering knuckles. All vehicles are equipped with power steering. The steering column is connected to the steering gear through an insuiated coupier. The steering coiumn is designed to coiiapse in the event of an accident.

Always turn the steering wheel to the straight ahead position, place the ignition switch in the Lock position and disable the airbag system (see Chapter 12) before working in the vicinity of the impact sensors, steering column or instrument panel to avoid the possibility of accidental deployment of the airbag, which could cause personal injury. 1 Disconnect the negative battery cable. Note: On models equipped with the Theftlock audio system, be sure the lockout feature is
turned off before performing any procedure which requires disconnecting the battery. 2 Using a number 30 Torx bit, remove the two screws that secure the airbag module to the steering wheel (see illustration). 3 Lift the airbag module carefully away from the steering wheel and disconnect the yellow airbag electrical connector. This is a two-part disconnection, as there is a plastic clip that must be removed before the connector can be disconnected (see illustra¬ tions). Remove the module. Warning: When carrying the airbag, module, keep the driver’s side of it away from your body, and when you place it on the bench, have the driver’s side facing up. 4 Remove the steering wheel nut (see illustration). 5 Mark the relationship of the steering wheel to the shaft (see illustration). 6 Install a steering wheel puller (available at most auto parts stores) and turn the center bolt until the wheel is free (see illustration).

Remove the steering wheel. Warning: Don’t allow the steering shaft to turn with the steering wheel removed. If the shaft turns, the airbag coil assembly (the mechanism which protects the airbag wiring when the steering wheel is turned) will become uncentered, which may cause the airbag harness to break when the vehicle is returned to service. 8 Installation is the reverse of removal. Before installing the steering wheel, make sure the airbag coil assembly is centered (see illustration). If it isn’t, see Chapter 12, Section 8, Step 14 for the centering procedure. Connect the airbag connector to the back of the airbag module just as it was before steering wheel removal, i.e. with the plastic locking device in place. Be sure to tighten the steering wheel nut and airbag screws to the torque listed in this Chapter’s Specifications. 9 Refer to Chapter 12 for the procedure to enable the airbag system.

Remove as much fluid from the reservoir as possible with a suction pump, then remove the return line (rubber hose connection with clamp) from the rack to the reservoir (see illustration). 7 Using a flare-nut wrench and a back-up wrench, disconnect the pressure hose from the pump. 8 Remove the pump mounting bolts and detach the pump from the engine, being careful not to spill the remaining fluid (see illustration).
Installation 9 If a new pump is to be instailed, the pulley will have to be transferred to the new pump. Use a power steering pulley puller (available at most auto parts stores) to remove the pulley and install it on the new pump (see illustrations). Note: Take note of how far the pulley was pressed onto the old pump’s shaft before removing the pulley. 10 If your new pump doesn’t come with a reservoir, you can swap your old one to the new pump. Remove the reservoir by pulling on the two sliding clips that hold the reservoir to the pump. Install a new 0-ring at the fluid connection and clip the reservoir onto the new pump. 11 Position the pump on the mounting bracket and install the bolts. 12 Connect the pressure and return lines to the pump. 13 Fill the reservoir with the recommended fluid and bleed the system, following the procedure described in the next Section.

19 Power steering system - bleeding 1 Following any operation in which the power steering fluid lines have been discon¬ nected, the power steering system must be bled to remove air and obtain proper steering performance. 2 With the front wheels turned all the way to the left and the ignition key OFF, check the power steering fluid level and, if low, add fluid until it reaches the Cold mark on the dipstick, 3 Start the engine and allow it to run at fast idle. Recheck the fluid level and add more if necessary to reach the Cold mark on the dipstick. 4 Bleed the system by turning the wheels from side-to-side, without hitting the stops. This will work the air out of the system. Don’t allow the reservoir to run out of fluid. 5 When the air is worked out of the system, return the wheels to the straight ahead position and leave the engine running for several minutes before shutting it off. Recheck the fluid level. 6 Road test the vehicle to be sure the
Chapter 10 Suspension and steering systems steering system is functioning normaiiy with no noise. 7 Recheck the fiuid ievei to be sure it’s up to the Hot mark on the dipstick whiie the engine is at normai operating temperature. Add fiuid if necessary.
20 Wheels and tires - general information Refer to illustration 20.1 Aii vehicies covered by this manuai are equipped with metric-size fibergiass or steei beited radiai tires (see illustration). The use of other size or type tires may affect the ride and handiing of the vehicie. Don’t mix different types of tires, such as radiais and bias belted, on the same vehicle, since handling may be seriously affected. Tires should be replaced in pairs on the same axle, but if only one tire is being replaced, be sure it’s the same size, structure and tread design as the other. Because tire pressure affects handling and wear, the tire pressures should be checked at least once a month or before any extended trips (see Chapter 1). Wheels must be replaced if they’re bent, dented, leak air, have elongated bolt holes, are heavily rusted, out of vertical symmetry or if the lug nuts won’t stay tight. Wheel repairs by welding or peening aren’t recommended. Tire and wheel balance is important to the overall handling, braking and perfor¬ mance of the vehicle. Unbalanced wheels can adversely affect handling and ride characteristics as well as tire life. Whenever a tire is installed on a wheel, the tire and wheel should be balanced by a shop with the proper equipment.

Wheel alignment - general information
Refer to illustration 21.1 A wheel alignment refers to the adjust¬ ments made to the wheels so they’re in proper angular relationship to the suspension and the ground. Wheels that are out of proper alignment not only affect steering control, but also increase tire wear. The adjustment most commonly required is the toe-in adjustment but camber adjustment is also possible (see illustration). Getting the proper wheel alignment is a very exacting process, one in which compli¬ cated and expensive machines are necessary to perform the job properly. Because of this, you should have a technician with the proper equipment perform these tasks. We will, however, attempt to give you a basic idea of what’s involved with wheel alignment so you can better understand the process and deal intelligently with the shop that does the work. Toe-in is the turning in of the wheels. The purpose of a toe specification is to

Chapter 10 Suspension and steering systems
ensure parallel rolling of the wheels. In a vehicle with zero toe-in, the distance between the front edges of the wheels will be the same as the distance between the rear edges of the wheels. The actual amount of toe-in is normally only a fraction of an inch. Incorrect toe-in will cause the tires to wear improperly by making them scrub against the road surface. On the front end, toe adjustment is controlled by the tie-rod end position on the tie-rod. On the rear, a special
tool Is required to adjust the position of the rear lateral link rod in its inner mount. Camber is the tilting of the wheels from the vertical when viewed from the front or rear of the vehicle. When the wheels tilt out at the top, the camber Is said to be positive (+). When the wheels tilt in at the top the camber is negative (-). The amount of tilt is measured in degrees from the vertical and this measurement is called the camber angle. This angle affects the amount of tire tread which
contacts the road and compensates for changes in the suspension geometry when the vehicle Is cornering or traveling over an undulating surface. Camber can be adjusted after the strut mounting holes have been elongated with a file. Camber adjustment, front or rear, must be done with the vehicle on the alignment rack, by an experienced technician. Cdister is not adjustable. If the caster angle Is not to specification, the suspension components must be checked for damage.

1 General information
2 Body - maintenance
Warning: The models covered by this manual are equipped with airbags. Aiways disable the airbag system (see Chapter 12) before working in the vicinity of the impact sensors, steering column or instrument panel. Failure to follow these procedures may cause accidental deployment of the airbag, which could cause personal injury. The airbag circuits are easily identified by yellow insulation covering the entire wiring harness. Do not use electrical test equipment on any of these wires or tamper with them in any way. Caution: On models equipped with a Theftlock audio system, be sure the lockout feature is turned off before performing any procedure which requires disconnecting the battery. These models feature a “unibody” construction, using a floor pan with front and rear frame side rails which support the body components, front and rear suspension systems and other mechanical components. Certain body components are particu¬ larly vulnerable to accident damage and can be unbolted and repaired or replaced. Among these parts are the body moldings, front fenders, doors, bumpers, the hood, trunk lid and all glass. Only general body maintenance practices and body panel repair procedures within the scope of the do-it-yourselfer are included in this Chapter.
1 The condition of your vehicle’s body is very important, because the resale value depends a great deal on it. It’s much more difficult to repair a neglected or damaged body than it is to repair mechanical compo¬ nents. The hidden areas of the body, such as the wheel wells, the frame and the engine compartment, are equally important, although they don’t require as frequent attention as the rest of the body. 2 Once a year, or every 12,000 miles, it’s a good idea to have the underside of the body steam cleaned. All traces of dirt and oil will be removed and the area can then be inspected carefully for rust, damaged brake lines, frayed electrical wires, damaged cables and other problems. The front suspension components should be greased after completion of this job. 3 At the same time, clean the engine and the engine compartment with a steam cleaner or water-soluble degreaser. 4 The wheel wells should be given close attention, since undercoating can peel away and stones and dirt thrown up by the tires can cause the paint to chip and flake, allowing rust to set in. If rust is found, clean down to the bare metal and apply an anti-rust paint. 5 The body should be washed about once a week. Wet the vehicle thoroughly to soften the dirt, then wash it down with a soft sponge and plenty of clean soapy water. If the surplus dirt is not washed off very carefully, it
7 9 10 20 24 23 13 14 4 3 8
can wear down the paint. 6 Spots of tar or asphalt thrown up from the road should be removed with a cloth soaked in solvent.7 Once every six months, wax the body and chrome trim. If a chrome cleaner is used to remove rust from any of the vehicle’s plated parts, remember that the cleaner also removes part of the chrome, so use it sparingly.
3 Vinyl trim - maintenance Don’t clean vinyl trim with detergents, caustic soap or petroleum-based cleaners. Plain soap and water works just fine, with a soft brush to clean dirt that may be ingrained. Wash the vinyl as frequently as the rest of the vehicle. After cleaning, application of a high-quality rubber and vinyl protectant will help prevent oxidation and cracks. The protectant can also be applied to weatherstripping, vacuum lines and rubber hoses, which often fail as a result of chemical degradation, and to the tires.
11 Upholstery and carpets maintenance 1 Every three months, remove the floormats and clean the interior of the vehicle (more frequently if necessary). Use a stiff whisk broom to brush the carpeting and
11-2 loosen dirt and dust, then vacuum the uphol¬ stery and carpets thoroughly, especially along seams and crevices. 2 Dirt and stains can be removed from carpeting with basic household or automotive carpet shampoos available in spray cans. Follow the directions and vacuum again, then use a stiff brush to bring back the “nap” of the carpet. 3 Most interiors have cloth or vinyl uphol¬ stery, either of which can be cleaned and maintained with a number of material-specific cleaners or shampoos available in auto supply stores. Follow the directions on the product for usage, and always spot-test any upholstery cleaner on an inconspicuous area (bottom edge of a back seat cushion) to ensure that it doesn’t cause a color shift in the material. 4 After cleaning, vinyl upholstery should be treated with a protectant. Note: Make sure the protectant container indicates the product can be used on seats - some products may make a seat too siippery. Caution: Do not use protectant on vinyicovered steering wheels. 5 Leather upholstery requires special care. It should be cleaned regularly with saddlesoap or leather cleaner. Never use alcohol, gasoline, nail polish remover or thinner to clean leather upholstery. 6 After cleaning, regularly treat leather upholstery with a leather conditioner, rubbed in with a soft cotton cloth. Never use car wax on leather upholstery. 7 In areas where the interior of the vehicle is subject to bright sunlight, cover leather seating areas of the seats with a sheet if the vehicle is to be left out for any length of time.

Body
Flexible panels (front and rear bumper fascia) 1 Remove the damaged panel, if hecessary or desirable. In most cases, repairs can be carried out with the panel installed. 2 Clean the area(s) to be repaired with a wax, grease and silicone removing solvent applied with a water-dampened cloth. 3 If the damage is structural, that is, if it extends through the panel, clean the backside of the panel area to be repaired as well. Wipe dry. 4 Sand the rear surface about 1-1/2 in beyond the break. 5 Cut two pieces of fiberglass cloth large enough to overlap the break by about 1-1/2 in. Cut only to the required length. 6 Mix the adhesive from the repair kit according to the instructions included with the kit, and apply a layer of the mixture approximately 1/8-inch thick on the backside of the panel. Overlap the break by at least 1-1/2 inches 7 Apply one piece of fiberglass cloth to the adhesive and cover the cloth with additional adhesive. Apply a second piece of fiberglass cloth to the adhesive and immedi¬ ately cover the cloth with additional adhesive insufficient quantity to fill the weave. 8 Allow the repair to cure for 20 to 30 minutes at 60-degrees to 80-degrees F. 9 If necessary, trim the excess repair material at the edge. 10 Remove all of the paint film over and around the area(s) to be repaired. The repair material should not overlap the painted surface. 11 With a drill motor and a sanding disc (or a rotary file), cut a “V” along the break line approximately 1/2-inch wide. Remove all dust and loose particles from the repair area. 12 Mix and apply the repair material. Apply a light coat first over the damaged area; then continue applying material until it reaches a level slightly higher than the surrounding finish. 13 Cure the mixture for 20 to 30 minutes at 60-degrees to 80-degrees F. 14 Roughly establish the contour of the area being repaired with a body file. If low areas or pits remain, mix and apply additional adhesive. 15 Block sand the damaged area with sandpaper to establish the actual contour of the surrounding surface. 16 If desired, the repaired area can be temporarily protected with several light coats of primer. Because of the special paints and techniques required for flexible body panels, it is recommended that the vehicle be taken to a paint shop for completion of the body repair.
Steel body panels See photo sequence
Repair of minor scratches 17
If the scratch is superficial and does not
penetrate to the metal of the body, repair is very simple. Lightly rub the scratched area with a fine rubbing compound to remove loose paint and built-up wax. Rinse the area with clean water. 18 Apply touch-up paint to the scratch, using a small brush. Continue to apply thin layers of paint until the surface of the paint in the scratch is level with the surrounding paint. Allow the new paint at least two weeks to harden, then blend it into the surrounding paint by rubbing with a very fine rubbing compound. Finally, apply a coat of wax to the scratch area. 19 If the scratch has penetrated the paint and exposed the metal of the body, causing the metal to rust, a different repair technique is required. Remove all loose rust from the bottom of the scratch with a pocket knife, then apply rust inhibiting paint to prevent the formation of rust in the future. Using a rubber or nylon applicator, coat the scratched area with glaze-type filler. If required, the filler can be mixed with thinner to provide a very thin paste, which is ideal for filling narrow scratches. Before the glaze filler in the scratch hardens, wrap a piece of smooth cotton cloth around the tip of a finger. Dip the cloth in thinner and then quickly wipe it along the surface of the scratch. This will ensure that the surface of the filler is slightly hollow. The scratch can now be painted over as described earlier in this Section.
Repair of dents 20 When repairing dents, the first job is to pull the dent out until the affected area is as close as possible to its original shape. There is no point in trying to restore the original shape completely as the metal in the damaged area will have stretched on impact and cannot be restored to its original contours. It is better to bring the level of the dent up to a point which is about 1/8-inch below the level of the surrounding metal. In cases where the dent is very shallow, it is not worth trying to pull it out at all. 21 If the back side of the dent is accessible, it can be hammered out gently from behind using a soft-face hammer. While doing this, hold a block of wood firmly against the opposite side of the metal to absorb the hammer blows and prevent the metal from being stretched. 22 If the dent is in a section of the body which has double layers, or some other factor makes it inaccessible from behind, a different technique is required. Drill several small holes through the metal inside the damaged area, particularly in the deeper sections. Screw long, self-tapping screws into the holes just enough for them to get a good grip in the metal. Now the dent can be pulled out by pulling on the protruding heads of the screws with locking pliers. 23 The next stage of repair is the removal of paint from the damaged area and from an inch or so of the surrounding metal. This is done with a wire brush or sanding disk in a drill motor, although it can be done just as
Chapter 11 effectively by hand with sandpaper. To compiete the preparation for fiiiing, score the surface of the bare metai with a screwdriver or the tang of a fiie, or driii smail hoies in the affected area. This wiii provide a good grip for the fiiler material. To complete the repair, see the subsection on filling and painting later in this Section.
Repair of rust holes or gashes 24 Remove all paint from the affected area and from an inch or so of the surrounding metal using a sanding disk or wire brush mounted in a drill motor. If these are not available, a few sheets of sandpaper will do the job just as effectively. 25 With the paint removed, you will be able to determine the severity of the corrosion and decide whether to replace the whole panel, if possible, or repair the affected area. New body panels are not as expensive as most people think and it is often quicker to install a new panel than to repair large areas of rust. 26 Remove all trim pieces from the affected area except those which will act as a guide to the original shape of the damaged body, such as headlight shells, etc. Using metal snips or a hacksaw blade, remove all loose metal and any other metal that is badly affected by rust. Hammer the edges of the hole in to create a slight depression for the filler material. 27 Wire brush the affected area to remove the powdery rust from the surface of the metal. If the back of the rusted area is acces¬ sible, treat it with rust inhibiting paint. 28 Before filling is done, block the hole in some way. This can be done with sheet metal riveted or screwed into place, or by stuffing the hole with wire mesh. 29 Once the hole is blocked off, the affected area can be filled and painted. See the following subsection on filling and painting.
Filling and painting 30 Many types of body fillers are available, but generally speaking, body repair kits which contain filler paste and a tube of resin hardener are best for this type of repair work. A wide, flexible plastic or nylon applicator will be necessary for imparting a smooth and contoured finish to the surface of the filler material. Mix up a small amount of filler on a clean piece of wood or cardboard (use the hardener sparingly). Follow the manufac¬ turer’s instructions on the package, otherwise the filler will set incorrectly. 31 Using the applicator, apply the filler paste to the prepared area. Draw the appli¬ cator across the surface of the filler to achieve the desired contour and to level the filler surface. As soon as a contour that approximates the original one is achieved, stop working the paste. If you continue, the paste will begin to stick to the applicator. Continue to add thin layers of paste at 20-minute intervals until the level of the filler is just above the surrounding metal. 32 Once the filler has hardened, the excess
Body
can be removed with a body file. From then on, progressively finer grades of sandpaper should be used, starting with a 180-grit paper and finishing with 600-grit wet-or-dry paper. Always wrap the sandpaper around a flat rubber or wooden block, otherwise the surface of the filler will not be completely flat. During the sanding of the filler surface, the wet-or-dry paper should be periodically rinsed in water. This will ensure that a very smooth finish is produced in the final stage. 33 At this point, the repair area should be surrounded by a ring of bare metal, which in turn should be encircled by the finely feathered edge of good paint. Rinse the repair area with clean water until all of the dust produced by the sanding operation is gone. 34 Spray the entire area with a light coat of primer. This will reveal any imperfections in the surface of the filler. Repair the imperfec¬ tions with fresh filler paste or glaze filler and once more smooth the surface with sandpaper. Repeat this spray-and-repair procedure until you are satisfied that the surface of the filler and the feathered edge of the paint are perfect. Rinse the area with clean water and allow it to dry completely. 35 The repair area is now ready for painting. Spray painting must be carried out in a warm, dry, windless and dust free atmosphere. These conditions can be created if you have access to a large indoor work area, but if you are forced to work in the open, you will have to pick the day very carefully. If you are working indoors, dousing the floor in the work area with water will help settle the dust which would otherwise be in the air. If the repair area is confined to one body panel, mask off the surrounding panels. This will help minimize the effects of a slight mismatch in paint color. Trim pieces such as chrome strips, door handles, etc., will also need to be masked off or removed. Use masking tape and several thickness of newspaper for the masking operations. 36 Before spraying, shake the paint can thoroughly, then spray a test area until the spray painting technique is mastered. Cover the repair area with a thick coat of primer. The thickness should be built up using several thin layers of primer rather than one thick one. Using 600-grit wet-or-dry sandpaper, rub down the surface of the primer until it is very smooth. While doing this, the work area should be thoroughly rinsed with water and the wet-or-dry sandpaper periodically rinsed as well. Allow the primer to dry before spraying additional coats. 37 Spray on the top coat, again building up the thickness by using several thin layers of paint. Begin spraying in the center of the repair area and then, using a circular motion, work out until the whole repair area and about two inches of the surrounding original paint is covered. Remove all masking material 10 to 15 minutes after spraying on the final coat of paint. Allow the new paint at least two weeks to harden, then use a very
11-3 fine rubbing compound to blend the edges of the new paint into the existing paint. Finally, apply a coat of wax.
6 Body repair - major damage 1 Major damage must be repaired by an auto body/frame repair shop with the necessary welding and hydraulic straight¬ ening equipment. 2 If the damage has been serious, it is vital that the structure be checked for proper alignment or the vehicle’s handling character¬ istics may be adversely affected. Other problems, such as excessive tire wear and wear in the driveline and steering may occur. 3 Due to the fact that all of the major body components (hood, fenders, etc.) are separate and replaceable units, any seriously damaged components should be replaced rather than repaired. Sometimes these components can be found in a wrecking yard that specializes in used vehicle components, often at considerable savings over the cost of new parts.
7 Hinges and locks - maintenance Once every 3000 miles, or every three months, the hinges and latch assemblies on the doors, hood and trunk should be given a few drops of light oil or lock lubricant. The door latch strikers should also be lubricated with a thin coat of grease to reduce wear and ensure free movement. Lubricate the door and trunk locks with spray-on graphite lubricant.
8 Windshield and fixed glass replacement Replacement of the windshield and fixed glass requires the use of special fast setting adhesive/caulk materials. These operations should be left to a dealer or a shop specializing in glass work.
9 Hood - removal, installation and adjustment Note: The hood is somewhat awkward to remove and install, at least two people should perform this procedure.
Removal and installation Refer to illustrations 9.3 and 9.4 1 Open the hood, then place blankets or pads over the fenders and cowl area of the body. This will protect the body and paint as the hood is lifted off. 2 Disconnect any cables or wires that will interfere with removal. 3 Make marks or scribe a line around the
These photos illustrate a method of repairing simple dents. They are intended to supplement Body repair - minor damage in this Chapter and should not be used as the sole instructions for body repair on these vehicles.
1
If you can’t access the backside of the body panel to hammer out the dent, pull it out with a slide-hammer-type dent puller. In the deepest portion of the dent or along the crease line, drill or punch hole(s) at least one inch apart...
2
... then screw the slide-hammer into the hole and operate it. Tap with a hammer near the edge of the dent to help ‘pop’ the metal back to its original shape. When you’re finished, the dent area should be close to its original contour and about 1/8-inch below the surface of the surrounding metal
3 Using coarse-grit sandpaper, remove the paint down to the bare metal. Hand sanding works fine, but the disc sander shown here makes the job faster. Use finer (about 320-grit) sandpaper to feather-edge the paint at least one inch around the dent area
4 When the paint is removed, touch will probably be more helpful than sight for telling if the metal is straight. Hammer down the high spots or raise the low spots as necessary. Clean the repair area with wax/silicone remover
5 Following label instructions, mix up a batch of plastic filler and hardener. The ratio of filler to hardener is critical, and, if you mix it incorrectly, it will either not cure properly or cure too quickly (you won’t have time to file and sand it into shape)
6 Working quickly so the filler doesn’t harden, use a plastic applicator to press the body filler firmly into the metal, assuring it bonds completely. Work the filler until it matches the original contour and is slightly above the surrounding metal
7 Let the filler harden until you can just dent it with your fingernail. Use a body file or Surform tool (shown here) to roughshape the filler
8 Use coarse-grit sandpaper and a sanding board or block to work the filler down until it’s smooth and even. Work down to finer grits of sandpaper - always using a board or block - ending up with 360 or 400 grit
9 You shouldn’t be able to feel any ridge at the transition from the filler to the bare metal or from the bare metal to the old paint. As soon as the repair is flat and uniform, remove the dust and mask off the adjacent panels or trim pieces
10 Apply several layers of primer to the area. Don’t spray the primer on too heavy, so it sags or runs, and make sure each coat is dry before you spray on the next one. A professional-type spray gun is being used here, but aerosol spray primer is available inexpensively from auto parts stores
11 The primer will help reveal imperfections or scratches. Fill these with glazing compound. Follow the label instructions and sand it with 360 or 400-grit sandpaper until it’s smooth. Repeat the glazing, sanding and respraying until the primer reveals a perfectly smooth surface
12 Finish sand the primer with very fine sandpaper (400 or 600grit) to remove the primer overspray. Clean the area with water and allow it to dry. Use a tack rag to remove any dust, then apply the finish coat. Don’t attempt to rub out or wax the repair area until the paint has dried completely (at least two weeks)

20 Wiper motor - check and replacement
Check Note: Refer to the wiring diagrams for wire colors and locations in the following checks. Keep in mind that power wires are generally larger in diameter and brighter colors, where ground wires are usually smaller in diameter and darker colors. When checking for voltage, probe a grounded 12-volt test light to each terminal at a connector until It lights; this verifies voltage (power) at the terminal. 1 If the wipers work slowly, make sure the battery is in good condition and has a strong charge (see Chapter 1). If the battery is in good condition, remove the wiper motor (see below) and operate the wiper arms by hand. Check tor binding linkage and pivots. Lubricate or repair the linkage or pivots as necessary. Reinstall the wiper motor. If the wipers still operate slowly, check for loose or corroded connections, especiaiiy the ground connection. If all connec¬ tions iook OK, replace the motor. 2 If the wipers fail to operate when activated, check the fuse. If the fuse is OK, connect a jumper wire between the wiper motor and ground, then retest. If the motor works now, repair the ground connection. If the motor still doesn’t work, turn the wiper switch to the HI position and check for voltage at the motor. If there’s voltage at the motor, remove the motor and check it off the vehicle with fused jumper
wires from the battery. If the motor now works, check for binding linkage (see Step 1 above). If the motor still doesn’t work, replace it. If there’s no voltage at the motor, check for voltage at the wiper control module. If there’s voltage at the wiper control module and no voltage at the at the wiper motor, check the switch for conti¬ nuity. If the switch is OK, the wiper control module is probably bad. 3 If the interval (delay) function is inoper¬ ative, check the continuity of all the wiring between the switch and wiper control module. If the wiring is OK, check the resis¬ tance of the delay control knob of the multi¬ function switch (see Section 8). If the delay control knob is within the specified resis¬ tance, replace the wiper control module. 4 If the wipers stop at the position they’re in when the switch is turned off (fail to park), check for voltage at the park feed wire of the wiper motor connector when the wiper switch is OFF but the ignition is ON. if no voltage is present, check for an open circuit between the wiper motor and the fuse panel. 5 If the wipers won’t shut off unless the ignition is OFF, disconnect the wiring from the wiper control switch. If the wipers stop, replace the switch. If the wipers keep running, there’s a defective limit switch in the motor; replace the motor. 6 if the wipers won’t retract below the hoodline, check for mechanicai obstructions in the wiper linkage or on the vehicle’s body which would prevent the wipers from parking. If there are no obstructions, check the wiring between the switch and motor for continuity. If the wiring is OK, replace the wiper motor.
Replacement Refer to illustrations 20.7, 20.8a, 20.8b, 20.8c, 20.10a, 20.10b and 20.12 7 Pry off the cover from the wiper arm retaining nuts, unscrew the nuts, detach the washer hoses and remove both wiper arms (see illustration). 8 Remove the retaining screws, the

If either of the circuits is not receiving voltage, inspect the wiring between the reiay and the fuse panel. 6 If both relay circuits are receiving voltage, depress the horn button and check the circuit from the relay to the horn button for continuity to ground. If there’s no conti¬ nuity, check the circuit for an open. If there’s no open circuit, replace the horn button. 7 If there’s continuity to ground through the horn button, check for an open or short in the circuit from the relay to the horn.
cruise control). 4 If the brake lights don’t come on or don’t shut off, correct the problem and retest the cruise control. 5 Inspect the cable linkage between the cruise control module and the throttle linkage. The cruise control module is located on the left (drivers) inner fenderwell of the engine compartment (see illustration). 6 Visually inspect the wires connected to the cruise control actuator and check for damage and broken wires. 7 The cruise control system uses a speed sensing device. The speed sensor is located in the transmission. To test the speed sensor see Chapter 6. 8 Test drive the vehicle to determine if the cruise control is now working. If it isn’t, take it to a dealer service department or an automotive electrical specialist for further diagnosis and repair.
Replacement Refer to illustration 21.9 8 To access the horns remove the plastic air deflector surrounding the hood latch assembly. 9 Disconnect the electrical connectors and remove the bracket bolts (see illus¬ tration). 10 Installation is the reverse of removal.
22 Cruise control system description and check Refer to illustration 22.5 1 The cruise control system maintains vehicle speed with an electronic servo motor located in the engine compartment, which is connected to the throttle linkage by a cable. The system consists of the electronic control module, brake switch, control switches, a relay, the vehicle speed sensor and associated wiring. Listed below are some general procedures that may be used to locate common cruise control problems. 2 Locate and check the fuse (see Sec¬ tion 3). 3 Have an assistant operate the brake lights while you check their operation (voltage from the brake light switch deactivates the

lower and raise the windows. The system consists of the control switches, the motors, regulators, glass mechanisms and associated wiring. 2 The power windows can be lowered and raised from the master control switch by the driver or by remote switches located at the individual windows. Each window has a separate motor which is reversible. The position of the control switch determines the polarity and therefore the direction of operation. 3 The circuit is protected by a fuse and a circuit breaker. Each motor is also equipped with an internal circuit breaker, this prevents one stuck window from disabling the whole system. 4 The power window system will only operate when the ignition switch is ON. In addition, many models have a window lockout switch at the master control switch which, when activated, disables the switches at the rear windows and, sometimes, the switch at the passenger’s window also. Always check these items before troubleshooting a window problem. 5 These procedures are general in nature, so if you can’t find the problem using them, take the vehicle to a dealer service department or other properly equipped repair facility. 6 If the power windows won’t operate, always check the fuse and circuit breaker first. 7 If only the rear windows are inoperative, or if the windows only operate from the master control switch, check the rear window lockout switch for continuity in the unlocked position. Replace it if it doesn’t have conti¬ nuity. 8 Check the wiring between the switches and fuse panel for continuity. Repair the wiring, if necessary. 9 If only one window is inoperative from the master control switch, try the other control switch at the window. Note; This doesn’t apply to the drivers door window. 10 If the same window works from one switch, but not the other, check the switch for continuity. 11 If the switch tests OK, check for a short or open in the circuit between the affected switch and the window motor.

23.12 If no voltage is found at the motor with the switch depressed, check for voltage at the switch
24.6 Check for voltage at the lock solenoid while the switch is operated
12 If one window is inoperative from both switches, remove the trim panel from the affected door and check for voltage at the switch and at the motor while the switch is operated (see illustration). 13 If voltage is reaching the motor, disconnect the glass from the regulator (see Chapter 11). Move the window up and down by hand while checking for binding and damage. Also check for binding and damage to the regulator, if the regulator is not damaged and the window moves up and down smoothly, replace the motor. If there’s binding or damage, lubricate, repair or replace parts, as necessary. Note: The window motor is an integral part of the window regulator assembly. See Chapter 11 for the removal procedures. 14 If voltage isn’t reaching the motor, check the wiring in the circuit for continuity between the switches and motors. You’ll need to consult the wiring diagram for the vehicle. If the circuit is equipped with a relay, check that the relay is grounded properly and receiving voltage. 15 Test the windows after you are done to confirm proper repairs.
by bi-directional solenoids located in the doors. The lock switches have two operating positions: Lock and Unlock. When activated, the switch sends a ground signal to the door lock control unit to lock or unlock the doors. Depending on which way the switch is activated, the control unit reverses polarity to the solenoids, allowing the two sides of the circuit to be used alternately as the feed (positive) and ground side. Some vehicles may have an anti-theft systems incorporated into the power locks. If you are unable to locate the trouble using the following general Steps, consult your a dealer service department or other qualified repair shop. 1 Always check the circuit protection first. Some vehicles use a combination of circuit breakers and fuses. 2 Operate the door lock switches in both directions (Lock and Unlock) with the engine off. Listen for the click of the solenoids operating. 3 Test the switches for continuity. Replace the switch if there’s not continuity in both switch positions. 4 Check the wiring between the switches, control unit and solenoids for continuity. Repair the wiring if there’s no continuity. 5 Check for a bad ground at the switches or the control unit. 6 If all but one lock solenoids operate, remove the trim panel from the affected door (see Chapter 11) and check for voltage at the solenoid while the lock switch is operated Cne of the wires should have voltage in the Lock position; the other should have voltage in the Unlock position (see illus¬ tration). 7 If the inoperative solenoid is receiving voitage, replace the solenoid. 8 If the inoperative solenoid isn’t receiving voltage, check for an open or short in the wire between the lock solenoid and the control unit. Note: It’s common for wires to break in the portion of the harness between the body and door (opening and closing the door fatigues and eventually breaks the wires).
24
Power door lock system description and check
Refer to illustration 24.6 The power door lock system operates the door lock actuators mounted in each door. The system consists of the switches, actuators, a control unit and associated wiring. Diagnosis can usually be limited to simple checks of the wiring connections and actuators for minor faults which can be easily repaired. Since this system uses an ^electronic control unit, in-depth diagnosis should be left to a dealership service department. The door lock control unit is located behind the instrument panel, to the right of the fuse box. Power door lock systems are operated
Electric rear view mirrors description and check
1 Electric rear view mirrors use tw motors to move the glass; one for up-and down adjustments and one for left-to-righ adjustments. 2 The control switch has a selectc portion which sends voltage to the left o right side mirror. With the ignition CN, engin' CFF, roil down the windows and operate th‘ mirror control switch through all function (left-right and up-down) for both the left anc right side mirrors. 3 Listen carefully for the sound of thr electric motors running in the mirrors. 4 If the motors can be heard but the mirro glass doesn’t move, there’s probably t problem with the drive mechanism inside the mirror. Remove and disassemble the mirro to locate the problem. 5 If the mirrors don’t operate and nc sound comes from the mirrors, check the fuse (see Section 3). 6 If the fuse is OK, remove the mirro control switch from its mounting withou disconnecting the wires attached to it. Turr the ignition ON and check for voltage at the switch. There should be voltage at one terminal. If there’s no voltage at the switch check for an opening or short in the wiring between the fuse panel and the switch. 7 If there’s voltage at the switch, disconnect it. Check the switch for continuity in all its operating positions. If the switch does not have continuity, replace it. 8 Re-connect the switch. Locate the wire going from the switch to ground. Leaving the switch connected, connect a jumper wire between this wire and ground. If the mirror works normally with this wire in place, repair the faulty ground connection. 9 If the mirror still doesn’t work, remove the cover and check the wires at the mirror for voitage with a test light. Check with ignition ON and the mirror selector switch on the appropriate side. Operate the mirror switch in ail its positions. There should be voltage at one of the switch-to-mirror wires in each switch position (except the neutral position). 10 If there’s not voitage in each switch position, check the wiring between the mirror and control switch for opens and shorts. 11 If there’s voltage, remove the mirror and test it off the vehicle with jumper wires. Replace the mirror if it fails this test (see Chapter 11).
