If a condition is encountered where the convertible top material flaps against the back curtain assembly, the condition can be corrected by installing a 250mm (approximately) piece of adhesive-backed pile (Part No. 20380766) between top and back curtains as shown in Illustration. The adhesive backing should be installed to the back curtain with the pile facing outboard.
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.
