Power Window Motor Test

If the power window switch is receiving proper current and ground, but the power window motor does not operate, proceed with the Power Window Motor Test. Refer to the appropriate wiring information for correct terminal identification.

1. Remove the front door trim panel and sound pad as necessary to gain access to power window motor wire harness connector. Refer to PANEL, DOOR TRIM, REMOVAL .
2. Disconnect the power window motor wire harness connector from the door wire harness.
3. Using two jumper wires, connect one wire to a battery (+) source and the other to a good ground (-).
4. Connect the negative (-) jumper wire to one of the window motor connector terminals.
5. Momentarily touch the positive (+) jumper wire to the other window motor connector terminal. When positive jumper wire is connected, the motor should rotate in one direction to move the window up or down. If the window is already all the way up or down, the motor will grunt and the inner door panel will flex when the window is actuated in that direction.
6. Reverse the jumper wires at the window motor connector terminals and the window should now move all the way through its travel in the opposite direction.
7. If the window motor does not move the glass up or down through its complete travel, replace the window motor.
