How to Repair a Stuck Rear Driver's Side Window

The rear driver's side windows on your vehicle may occasionally become stuck in either the closed or open position. The usual causes of this malfunction include the untimely failure of the window regulator or window motor. The window can also fall off or become stuck on its track if the glue holding the window to the track fails or if the track is obstructed by debris. Diagnosing and repairing this problem necessitates the removal of the interior door panel and trim.

Instructions

1

Turn the ignition key to the "On" position and attempt to operate the rear driver's side power windows. If you can hear the motor operating but the window won't move up or down, the window may be stuck on its track. If you can't hear the motor operating, the motor may need replacement. Check the fuses for the power windows before attempting to remove the window motor.

2

Disconnect the negative terminal cable from the battery with a wrench. This will decrease the likelihood of shock and prevent the battery from being drained.

3

Open the rear driver's side door. Remove the interior door panel and trim. The method for removing the panel and trim will vary depending on the vehicle. Consult your vehicle's service manual and be sure to keep track of all clips and screws.

4

Inspect the window's track for signs of obstruction. You may need to apply a liberal amount of lithium grease to the track. If the window is off-track, clean the window of all adhesive and apply urethane-based glue to the window's mounting point. Reattach the window to the mounting point and leave the window undisturbed in the up position for one to two days.

5

Inspect the window regulator and motor. The window regulator will need to be replaced if the cables are snapped or frayed. If the window motor does not work, it will also need to be removed. Methods for removing both components may vary depending on the vehicle.

6

Reattach the door panel and trim to the rear driver's side door when finished. Close the door and reattach the negative terminal cable to the battery.
