CAMPAIGN: PULSE WIPER MOTOR RELAY CAPACITOR MAY FAIL
MODELS: 1983 Rivierias Equipped With Optional Delco/Bose Sound System and Windshield Wiper Low Speed Delay Feature
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.
In order to avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair his vehicle as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owner is being instructed to contact the nearest Buick Zone Office if his dealer does not remedy the condition within five (5) days of the agreed service date. If the condition is not remedied within a reasonable time, he is 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 Rivieras equipped with Delco/Bose radio sound systems and the windshield wiper low speed delay (pulse wipe) features. These vehicles have a noise suppression capacitor in the wiper motor delay relay which may overheat during operation of the delay feature. This condition could result in lose of windshield wiper operation and under certain conditions could result in an underhood fire. Such a fire could, in time, spread to the paseenger compartment and cause burn injuries to occupants remaining in the vehicle.
DEALER ACTION
To prevent the possibility of this condition occurring in vehicles involved, wiper motor pulse relay capacitor is to be removed as instructed in the Technical Procedure of this Bulletin.

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.
