Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, screwdriver set, trim removal tools.
Ensure the vehicle is in park and powered off before beginning work.
Disconnect the 12V battery to prevent any electrical shorts.

2. Remove Door Panel

Use trim removal tools to carefully pry off the door panel, starting from the bottom and working upward to avoid damage.
Remove any screws securing the panel, typically located near the door handle and armrest.
Disconnect any electrical connectors for speakers or switches from the back of the door panel.

3. Inspect and Test Window Motor

Locate the window motor inside the door, typically at the bottom.
Disconnect the wiring harness from the motor.
Using a multimeter, check for voltage at the motor connector when the window switch is activated.
- If voltage is present (approximately 12V), the motor may be faulty.
- If no voltage is detected, trace back to the switch and check its functionality.

4. Replace Window Motor (if faulty)

If the window motor is determined to be faulty, unscrew the motor from its mounting.
Carefully remove the motor from the window regulator assembly.
Install the new motor by aligning it with the mount and securing it with screws.
Reconnect the wiring harness to the new motor.

5. Reassemble Door Panel

Reconnect any electrical connectors for switches and speakers.
Align the door panel back onto the door frame and press firmly to snap it into place.
Reinsert screws removed during disassembly.
Reconnect the 12V battery and test the window operation.
