Defect and Vehicles Involved

DEFECT INVOLVED

General Motors has decided that a defect which relates to motor vehicle safety exists in all 1994 Chevrolet and GMC C/K model vehicles. These vehicles were built with the polarity of the wiring for the zero adjust brake switch reversed from what was specified on the switch drawing. With the reversed polarity, the contacts in the brake switch can wear out prematurely. The brake switch will perform normally until the brake switch contacts wear out. When worn out, the contacts fail to close when the brake pedal is pressed. This results in the loss of the brake lamps without any warning to the driver, which could fail to warn a following driver that the vehicle is braking and could lead to a vehicle accident,

To prevent the possibility of this condition occurring, dealers are to replace the brake switch and reverse the wiring.

VEHICLES INVOLVED





Involved are all 1994 Chevrolet and GMC C/K model vehicles built within the VIN breakpoints as shown.

Important:
