Rear Door Glass Inoperative or Operates Erratically due to Window Regulator Becoming Disengaged from Door Glass

Some customers may comment the rear door glass is inoperative or displays erratic operation.

The condition may be caused by excessive fore and aft movement of the door glass between the window run channels.

To correct this condition refer to service procedure in this bulletin to adjust the front and/or rear door glass window run channels.

1. Operate affected window regulator to full down position, using the window crank or switch on power equipped vehicles.

•	If window regulator does not operate refer to the Doors/Windows/Mirrors section in the applicable model year Body/Electrical Volume I Service Manual for further electrical diagnosis or regulator replacement.

•	If window regulator does operate and the glass does not move or if the glass goes down with the regulator proceed to next step.

Important: The door glass may or may not move with the regulator. Confirm disengagement of the regulator by moving the glass upward or downward by hand.

2. Remove interior and exterior door panels. Refer to Doors/Windows/Mirrors section in the applicable model year Body/Electrical Volume I Service Manual.
3. Move door glass to the half down position and push the door glass fore and aft within the window run channels inspecting for fore and aft movement of the door glass. Repeat this with the glass as close to the full down position as possible.
4. If it is determined that fore and aft movement of the door glass exists in either the half down or full down positions, proceed to step 5. If fore and aft movement of the door glass does not exist proceed to step 11.




Important: You must re-evaluate the operation of the door glass after each adjustment. Perform only the adjustments that are necessary to provide smooth operation of the door glass while eliminating fore and aft movement of the door glass within the run channels.

5. Remove front run channel lower retaining bolt and place a 2 mm thick washer P/N 11035625 (or equivalent) between the run channel and door.
6. Reinstall front run channel retaining bolt.
7. Operate window from full up to full down position by hand to determine if the door glass operates smoothly and re-evaluate the fore and aft movement of the door glass between the front and rear window run channels. If door glass still displays fore and aft movement proceed to next step. If fore and aft movement has been eliminated proceed to step 11.



8. Loosen rear run channel retaining bolts and move the bottom of the run channel forward slightly.
