DOOR GLASS DOESN'T SEAL SERVICE FOR 2 DOOR CONVERTIBLE
VEHICLES AFFECTED: 1983 - 1990 J67 STYLE
REASON (1986 - 1989)
To replace composite (steel and plastic) blow out clip when door window closes with glass resting on outboard edge of clip and not sealing at roof rail seal or quarter window sash seal and also causing misalignment of door glass to quarter window.
(1990 and prior to 1986)
For vehicles without blow out clip. Install if door glass pulls away from seals during high speed travel or turbulent winds, causing intermittent air leaks and wind noise around door glass.
Also, to repair broken or inoperative plastic blow out clip.
SERVICE PARTS REQUIRED:
Plastic blow out clip - part number 125049B5 Centre rail seal retainer - part numbers 20498176 RH, 20498177 LH
REMOVE CENTRE RAIL SEAL RETAINER: - Figure 1
Remove screw from seal hold down tab. Partially open folding top to allow access to seal retainer screws and remove. Slowly remove centre seal retainer from roof rail, being careful not to damage the foam tape sealer on top edge of retainer. A thin scraper may help in this process.

INSPECT FOR PROPER OPERATION: Figure 2
Check #1
With door window in full-up position, close door completely several times. Top of window glass should go behind clip (between clip and rubber seal) every time. If not, then adjust door glass rear up-stop block as described below to slightly lower top of glass so that it will snap under and behind clip. Do not over adjust or glass will not seat to top rail seals.
Check #2
Also, with door fully closed the window should open then close full-up with window glass inside of clip as above. If not, then adjust door glass rear up-stop channel as described below to move top of window slightly inboard.

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.
