INTERMITTENT DASH BRAKE TELLTALE LIGHT OPERATION

VEHICLES AFFECTED: 1986-89 E

Some 1986-1989 Toronado, Trofeo, Riviera, and Reatta vehicles may experience a condition of dash brake telltale light stays on, or inoperative with parking brake set. This condition may be caused by a cracked brake switch.

To correct this condition replace the park brake switch with P/N 3521242.

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.
