Condition: Some 1991 B-cars may have a wavy or warped front door lower reveal molding cover (Mirror patch).
Cause: The plastic material may be deformed by heat.
Correction: Replace the cover with a new part (P/N 16612564 for LH; 16612565 for RH) using the following procedure:
Parts are currently available from GMSPO.
1. Remove retaining screw from front of cover.
2. Pull the forward edge of the cover away from the door and using an appropriate tool (i.e. J-24595-C), pry the push-in molding fastener from the door.
3. Slide the cover forward to disengage it from the upper and lower reveal moldings.
4. To ease installation, trim the tip of the push-in fastener off of the new part (remove approximately 1/4 inch or 6mm).
5. Position the new cover under the belt molding, then under the upper reveal molding, and slide it rearward into position.
6. Push the push-in fastener into the hole in the door and install the retaining screw.

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.
