Door Window Motor Replacement
Any vehicle equipped with electric windows has an electric motor in each door. When the driver or a passenger pushes the window-switch control panel, the window raises and lowers.
Intermittent electric window operation is often caused by a wiring problem or switch failure. The wiring harness that carries power to each door flexes each time the door is opened and closed. This motion can, over time, cause this harness to fatigue and fail.
To replace the door window motor, the inner door trim panel must be removed. Next, the door window regulator is separated from the window glass. Then the electric motor and door window regulator are removed from door, and the window-switch control panel and electric motor are separated. The electric motor is replaced, and the door components are reassembled in reverse order.
