Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working.
Tools required: Socket set, trim removal tool, multimeter, OBD-II scanner.

2. Remove Door Panel

Use a trim removal tool to carefully pry off any trim pieces covering the door panel screws.
Remove screws securing the door panel (location can vary; typically found near the handle and along the bottom).
Gently pull the door panel away from the door frame, releasing any clips. Be careful not to damage the clips or wiring.

3. Inspect and Test Window Motor

Locate the window motor and connector behind the door panel.
Use a multimeter to test the motor for voltage when the window switch is activated.
If no voltage is detected, troubleshoot the wiring or switch as needed.
If voltage is present but the motor does not operate, the motor may need replacement.

4. Replace Window Motor/Regulator (if necessary)

If the motor is determined to be faulty, remove the screws securing the motor to the regulator.
Disconnect the motor connector.
If the window regulator is also damaged, remove it by unscrewing it from the door frame.
Install the new window motor or regulator in reverse order, ensuring all connections are secure.

5. Reassemble Door Panel

Carefully position the door panel back onto the door frame.
Reinsert all screws and ensure clips are properly seated.
Reattach trim pieces.
Reconnect the vehicle’s battery.
