Power Window Repair: Replacing the Motor

Having power windows in a vehicle is a wonderful convenience, but as these windows function electrically, they may become faulty and if this happens, you need to look into power window repair as soon as possible.

Power windows are controlled by a window motor. A control switch and window regulator also form part of the set up. Once the control switch is pressed, the window is driven in a given direction by an electrical current.

In order to remove and replace a faulty power window motor, the door panel and select components need to be removed. Raise the window if possible before you begin to work on removing the door panel.

Step 1. Getting to the Motor

Disconnect the battery for safety. Remove the door handle and armrest screws with a screwdriver, and then remove the door handle and armrest. Check to see if your vehicle has a switch panel in the main door panel. Remove this switch panel if it is present. If a switch panel is not present, you must remove the entire door panel. Find the panel mounting bolts and remove them. Remove all electrical connections in order to completely separate the panel from the door. Then, remove the door panel completely. Remove the switch panel which will now be located within the door itself. Remove the sound and weather insulator sheet if it is present. You will now be able to easily see all of the inner workings of the door.

Step 2. Locating the Motor and Connector

You will find the power window motor positioned between the lower right area of the door and the center of the door. Disconnect the motor from the main wiring harness. Remove the motor by releasing it from the regulator gears. Locate the connector.

Step 3. Checking the Motor

Position a test light into either side of the connector. Turn the ignition key to the on position but do not start the vehicle. Press the switch to open and to close position. The test light will light up if the motor’s electrical circuit is functional.

Step 4. Replacing the Motor

You need to remove the motor if its electrical circuits are not functioning. Tape the window in place first to prevent it from sliding into the door once the motor has been removed. Remove the mounting bolts of the window regulator with a socket wrench. Remove the window regulator and replace with a new unit. Replace the power window motor by fitting it into the regulator gears. Check to see if you need to make any minor adjustments to the window rails.

Step 5. Reassembling the Door

Reassemble door by pressing to engage all the pop rivets. Press gently to ensure that each rivet has been driven home. Replace the door handle and armrest and screw them in place. Reconnect the battery. Turn on ignition to gauge if the motor is functioning correctly
