Before you proceed with this diagnosis, confirm proper switch operation. See Power Window Switch .
- Disconnect and isolate the battery negative cable. Remove trim panel from the door with the inoperative power window.
- Unplug the power window motor wire harness connector. Apply 12 volts across the motor terminals to check its operation in one direction. Reverse the connections across the motor terminals to check the operation in the other direction. Remember, if the window is in the full up or full down position, the motor will not operate in that direction by design. If OK, repair the circuits from the power window motor to the power window switch as required. If not OK, replace the faulty motor.
- If the motor operates in both directions, check the operation of the window glass and lift mechanism through its complete up and down travel. There should be no binding or sticking of the window glass or lift mechanism, through the entire travel range. If not OK, check the window glass, track, and regulator for sticking, binding, or improper adjustment.
