Disconnect the window switch connector and test it for continuity using a multimeter.
If faulty, replace the window switch.

4. Window Motor Inspection

With the door panel removed, locate the window motor.
Disconnect the motor’s electrical connector and test for power using a multimeter while activating the window switch.
If there is power but the motor does not operate, replace the window motor.
