CAMPAIGN: W/S WIPER MOTOR RELAY CAPACITOR MAY FAIL

SUBJECT: 1983 ELDORADO AND SEVILLE (EQUIPPED WITH DELCO/BOSE RADIO SOUND SYSTEM AND CONTROLLED CYCLE WIPER SYSTEM) WINDSHIELD WIPER MOTOR RELAY CAPACITOR MAY FAIL

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately repair within sixty (60) days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.

To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owners are being instructed to contact the nearest Cadillac Zone Off ice if the dealer does not remedy the condition within five (5) days of the agreed upon service date. If the condition is not remedied within a reasonable time, owners are instructed on how to contact the National Highway Traffic Safety Administration.

Defect Involved

General Motors has determined that a defect which relates to motor vehicle safety exists in some early production 1983 Cadillac Eldorados and Sevilles equipped with a Delco/Bose radio sound system and a controlled cycle (delay) windshield wiper system. These vehicles have a noise suppression capacitor in the windshield wiper motor delay relay which may overheat during operation of the delay feature. This condition could result in loss of windshield wiper operation and under certain conditions could result in an underhood fire. Such a fire could, in time, spread to the passenger compartment and cause burn injuries to occupants remaining in the vehicle.

To prevent the possibility of this condition occurring in vehicles involved, the windshield wiper motor delay relay capacitor is to be removed as instructed in the Service Procedure of this bulletin.

Dealer Campaign Responsibility

Dealers are to service all vehicles subject to this campaign, regardless of mileage, age of vehicle, or ownership, from this time forward.

Dear Cadillac Owner:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

General Motors has determined that a defect which relates to motor vehicle safety exists in some early production 1983 Eldorados and Sevilles equipped with a Delco/Bose radio sound system and a controlled cycle (delay) windshield wiper system. These vehicles have a noise suppression capacitor in the windshield wiper motor delay relay which may overheat during operation of the delay feature. This condition could result in loss of windshield wiper operation and under certain conditions could result in an underhood fire. Such a fire could, in time, spread to the passenger compartment and cause burn injuries to occupants remaining in the vehicle.

To prevent the possibility of this condition occurring on your vehicle, please contact your Cadillac Dealer to arrange a service date to have your vehicle corrected by modifying the windshield wiper motor delay relay. This service will be perf ormed at no charge to you.

Instructions for making this correction have been sent to your Cadillac Dealer. The labor time necessary to perform this correction is approximately 10 minutes. Please allow additional time for the dealer to process your vehicle. Until you have your vehicle corrected do not use the windshield wiper delay feature. When it is necessary to use the windshield wiper system, you should only use the medium or high position.

Your Cadillac Dealer is best equipped to provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and they do not remedy this condition on that date or within five days, we recommend you contact your nearest Cadillac Zone Off ce, either in person or by telephone for assistance. The zone office will assist you and your dealer in getting your vehicle corrected. The locations and telephone numbers of the zone offices are listed in your Owner's Manual.

After contacting your dealer and the zone off ice, if you are still not satisfied that we have done our best to remedy this condition without charge within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, S.W., Washington, D.C. 20590, or call 800- 424-9393 (Washington, D.C. residents use 426-0123).

The enclosed Owner Identification Card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage-paid Owner Identification Card and returning it to us. This will assist us in correcting all affected vehicles and will eliminate the necessity for contacting you during any subsequent follow-up notification.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your safety and continued satisfaction with our products.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
