CAMPAIGN:DRIVER'S WINDOW SWITCH OVERHEATING
1984-1985 ELDORADO CONVERTIBLES
TO: ALL GENERAL MOTORS DEALERS
CONDITION:
---------
General Motors of Canada has determined that a defect, which relates to motor vehicle safety may exist in some 1984 and 1985 Eldorado convertible models.
Water or snow dripping onto the driver's side window switch assemblies may cause an electrical short which can potentially cause the switches to overheat. This overheating may result in a fire in the door panel area.
DEALER ACTION
To correct this condition, Dealers are to replace the two window switch assemblies on all vehicles involved with those of a new design. In addition, on 1984 models only, Dealers will be required to replace the driver's side window switch connectors with newer type connectors.

All 1984 and 1985 Eldorado convertibles require this campaign. All affected vehicles have been identified by the VIN listing provided to involved Dealers with this bulletin. Any Dealer not receiving a listing was not shipped any of the affected vehicles.

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.
