CAMPAIGN:HEADLIGHT SWITCH BREAKS - REPLACE SWITCH

MODEL AND YEAR: 1987 CHEVROLET CORSICA MODELS

TO: ALL CHEVROLET DEALERS

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1987 Chevrolet Corsica model vehicles. These vehicles are part of a product exposure program developed by Chevrolet. All vehicles are owned by General Motors Acceptance Corporation and leased to dealers or daily rental fleets. These vehicles may have been produced with a headlight switch that may experience fracture of the pushbutton escutcheon attachment. This may result in the headlight pushbutton not latching in the "ON" position. The inability to turn on the headlights under severe weather or nighttime driving conditions could reduce driver visibility which might result in a vehicle crash without prior warning.

Correction will consist of installation of a new headlight switch.

VEHICLES INVOLVED

Involved are all 1987 Chevrolet Corsica model vehicles built within the following Vehicle Identification Number (VIN) breakpoints.

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.
