The air conditioning condensers in some 1987-88 "L" cars may have been punctured by a screw from the lower air deflector (See Figure 1).
For this reason future production parts will eliminate the inboard attachments.
If an interference is noted between the condenser and deflector attaching screw on the subject vehicles, remove the two inboard screws.
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.
