Disconnect the electrical connector from the window switch.
Test the switch with a multimeter; if it’s faulty, replace it with a new switch.
Reassemble the door panel.

4. Test and Replace Window Motor (if necessary)

If the switch is functioning, use a multimeter to check for power at the motor connector when the switch is pressed.
If there is power but the motor does not operate, remove the motor from the door.
Install a new motor if the old one is defective. Follow the manufacturer’s instructions for installation.
Reconnect the power window motor and reassemble the door panel.

5. Reconnect Battery and Test
