One common cause of power windows that do not close is a defective switch, which you can replace by removing the switch from the door panel, disconnecting the cable and installing a new switch. Before changing the switch, make sure the window lock switch is off, and the fuse is working.
- Check the lock switch and fuse
Before replacing the switch, take time to check the fuse and the window lock switch. If either of these are a problem, none of the windows in the vehicle operate.
- Remove the switch from the switch panel
Locate and remove any screws that hold the switch in place. In newer vehicles, the switch panel often pops out of its housing.
- Remove the door panel if necessary
With some cars, you must remove the door panel. Remove the door handles and armrests by removing screws. Gently pull the panel to detach it from the door frame. Work slowly and carefully to disconnect any electrical connections.
- Replace the switch
Purchase a replacement switch from an auto parts store. Replace the switch that is not functioning with the new one.
- Reassemble the door
Reverse the steps to reassemble the door. Make the necessary electrical connections. Pop the panel fasteners into place. Replace any hardware that was removed to access the switch or remove the door panel.
