Solution

1. Preparation

Gather necessary tools: trim removal tool, screwdriver set, multimeter.
Ensure the vehicle is turned off and parked safely.
Disconnect the 12V battery to avoid electrical shock.

2. Remove Door Panel

Use a trim removal tool to carefully pry off the door panel clips.
Remove screws in the armrest and around the door handle using the appropriate screwdriver.
Disconnect any electrical connectors to the door panel and carefully lift it off.

3. Inspect Window Motor and Wiring

Locate the window motor and inspect it for any visible damage or wear.
Use a multimeter to test the voltage at the motor connector when the window switch is activated. The voltage should be approximately 12V.
If no voltage is present, trace the wiring back to the switch and fuse for continuity.

4. Replace Window Motor (if necessary)

If the motor is defective, remove the three bolts securing it to the window regulator.
Disconnect the motor connector and install the new motor in the reverse order.
Reattach the bolts and ensure they are torqued to factory specifications.

5. Reassemble Door Panel

Reconnect all electrical connectors to the door panel.
Align the door panel and press down to secure the clips.
Reinstall screws in the armrest and around the door handle.

6. Reconnect Battery and Test

Reconnect the 12V battery.
Test the window operation using the window switch and ensure all windows function correctly.
