For 1990-2009 cars

# CAMPAIGN:LAMP CONTROL MODULE

#### SUBJECT: LAMP CONTROL MODULE

#### MODELS: 1995 Pontiac Bonneville SE and SSE

#### TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain 1995 Pontiac Bonneville model vehicles. Some of these vehicles were assembled with Lighting Control Modules which may experience excessive current leakage due to damaged surface mounting capacitors. This condition could result in a loss of head lamps and park lamps. Sudden loss of head lamp lighting could reduce driver visibility, which could result in a vehicle crash without prior warning.

In addition, the potential also exists that the head lamps cannot be turned off or that they could turn on while the vehicle is parked. Both of these conditions would result in loss of battery state of charge and the inability to restart the vehicle.

To prevent the possibility of these conditions from occurring, dealers are to replace the lamp control module on involved vehicles.

#### VEHICLES INVOLVED:

Involved are the following 1995 Pontiac Bonneville model 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.
