DRIVERS DOOR WINDNOISE REINSTALL RUN CHANNEL RETAINER

SUBJECT: DOOR WINDNOISE - REINSTALL THE RUN CHANNEL RETAINER

MODEL/YEARS: 1990-92 TORONADO/TROFEO

Some 1990-92 Toronados and Trofeos may exhibit an undesirable wind noise from the front door window area.

To repair this condition perform the following procedure:

1. With the window in the full down position, start at the top front corner of the window opening. Grasp the window run channel weatherstrip with your hands and gently pull the weatherstrip out of the retainer (from the mirror area to the top rear corner of the window opening).

2. Inspect for a gapping condition between the window run channel molding/retainer and the forward window frame applique molding (the black molding on the leading edge of the door frame). Refer to View B of the illustration on the back of this bulletin.

Note: If no gapping condition exists, skip steps 3 and 4.

3. Remove the screws retaining the window run channel retainer in the door frame.

4. With the aid of an assistant, press the window run channel retainer tightly inboard against the window frame applique molding. With the run channel retainer tight against the applique molding, reinstall the screws. (It may be necessary to drill new holes.)

5. With a large marble sized ball of dum-dum, bridge all three sides of the window run channel retainer to the door window frame (at end of channel near mirror). Smooth out the dum-dum evenly to avoid a lump. Refer to View A of the illustration.

6. Press the window run channel weatherstrip back into the retainer. With the aid of a screwdriver or putty knife, make sure the weatherstrip outboard edge is properly seated in the run channel retainer and the inside lip is touching the inside door frame garnish molding evenly the full length.

7. Reinspect and road test the repair to ensure that the wind noise has been eliminated and the window run channel weatherstrip is evenly positioned both from the outside and the inside of the door.

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.
