SERVICE PROCEDURE

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

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.

operation of the door glass while eliminating fore and aft movement of the door glass within the run channels.
