Some 1990 or 1991 GEO Storms may exhibit a condition where the headlamps activate by themselves. This is more likely to happen in cold weather with the car parked overnight and often results in a dead battery.
To correct this situation, it is necessary to replace both the headlamp switch and the turn signal/combination switch.

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.
