Solution

1. Preparation

Tools Required: Socket set, Phillips screwdriver, flathead screwdriver, multimeter, wire stripper/crimper, safety glasses, and gloves.
Disconnect the negative battery terminal to prevent electrical shock.

2. Remove the Door Panel

Use a flathead screwdriver to carefully pry off any decorative trim around the door handle and window switches.
Unscrew all screws securing the door panel, including those hidden beneath trim pieces.
Gently pull the door panel away from the door frame, starting at the bottom and working upwards, to release the clips. Be cautious of any wiring connected to the switches.

3. Inspect and Test the Window Motor

Locate the window motor and regulator assembly.
Disconnect the motor’s electrical connector.
Use a multimeter to test for power at the connector while pressing the window switch. If power is present, the motor may need replacement.
If no power is detected, trace the wiring back to the switch and check for continuity.

4. Replace the Window Motor (if necessary)

If the motor is faulty, remove the screws securing the motor to the regulator.
Detach the motor from the regulator and replace it with a new motor, securing it with the screws.
Reconnect the electrical connector to the new motor.

5. Reassemble the Door Panel

Reconnect any wiring for the switches and secure the door panel back onto the door frame.
Reinstall all screws and snap the trim pieces back into place.
Reconnect the negative battery terminal.
