CAMPAIGN: STEERING WHEEL REDUNDANT RADIO CONTROLS. Chevrolet Lumina 1995

Subject: PRODUCT CAMPAIGN 96-C-27 - STEERING WHEEL REDUNDANT ---------------------------------------------------

Model and Year: RADIO CONTROLS (RPO UK3) 1995 CHEVROLET MONTE CARLO ---------------------------------------------------

To: All Chevrolet Geo Dealers

-------------------------

General Motors has determined that certain 1995 Chevrolet Monte Carlo model vehicles may have been assembled with steering wheel redundant radio control wires pinched between the steering wheel inner foam and the air bag inflator module backing plate. The insulation on the wires may wear away over time allowing for a short to ground. If a short to ground were to occur, the radio controls may become inoperative and noise may be emitted from the steering column. There is also a remote possibility that the air bag could inadvertently deploy.

To prevent the possibility of these conditions occurring, dealers are to install a new steering wheel redundant control wire harness. The new harness will also be rerouted to eliminate possible pinching between components. Vehicles which have exhibited any of the steering wheel redundant controls operating incorrectly will also have the steering wheel redundant control/supplemental inflatable restraint coil replaced.

VEHICLES INVOLVED

Involved are certain 1995 Chevrolet Monte Carlo models built within the following 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.
