Some 1990 Toronados and Trofeos built prior to VIN 301087 have a rear window lower reveal moulding which lacks a close-out flap. The flap bridges the gap from the rear window to the front of the deck lid and hides the attaching screws of the moulding itself.
Replace the moulding by opening the trunk and removing five screws (refer to New Product Information, Section 10-2) and the existing moulding. Install a new moulding, P/N 20727550.
Use most applicable Labour Operation and time from the Canadian Labour Time Guide.
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.
