Solution

1. Preparation

Gather necessary tools: trim removal tools, socket set, multimeter, and electrical contact cleaner.
Ensure the vehicle is in a safe and stable position, with the ignition off.
Disconnect the 12V battery to prevent any electrical shorts while working.

2. Remove Door Panel

Use trim removal tools to carefully pry off the door panel clips without damaging the panel.
Remove screws (usually located near the door handle and bottom of the panel) using a socket set.
Gently lift the door panel upwards to detach it from the window sealing grommet and set it aside.

3. Inspect Window Motor and Wiring

Locate the window motor and visually inspect it for any signs of damage or corrosion.
Use a multimeter to test the motor's voltage while operating the switch. If there’s no power, check the wiring harness for continuity.
Clean any corroded connectors with electrical contact cleaner to ensure good connectivity.

4. Replace Window Motor (if necessary)

If the motor is found faulty, disconnect it from the wiring harness and remove the mounting screws.
Install the new window motor by reversing the removal steps, ensuring to align it properly.
Reconnect the wiring harness securely.

5. Reassemble Door Panel

Reattach the door panel by aligning it back into the grooves and pressing it until it clicks into place.
Replace all screws removed earlier to secure the panel.
Reconnect the 12V battery and test the window operation again.
