VEHICLES AFFECTED: 1992 "K" MODELS WITHOUT SUNROOF
Some 1992 Sevilles may experience above normal roof panel noise during a rain storm. This may be caused by insufficient adhesion of the roof outer panel to the roof inner panel bows.
To correct this condition remove headliner assembly (reference 1992 Service Information Manual Section 10-9- 2). If breakage of the headliner rear locator occurs, replace with P/N 3635951.
Next, install the following material in the locations shown in Figure 1.
1. Utilize an adhesive such as 3M Hood Flutter Repair Kit (P/N 081105 or equivalent) or Kent Industries Uri- Foam (P/N 10-600 or equivalent) to bond the roof bows to the roof outer panel at the locations designated by the 21 silver dollar size drops shown in illustration.
2. Apply sound deadener pads (Kent Industries P/N 90225 or equivalent) to roof outer panel in the six large openings of roof inner panel bows; cut pads to fit. Secure with adhesive provided or recommended by supplier.
3. Reinstall the headliner (reference 1992 Service Information Manual Section 10-9-2).

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.
