Solution

1. Preparation

Tools Required: None specifically required; however, a flat screwdriver may be useful for panel removal.
Ensure the vehicle is parked and turned off.
Disconnect the 12V battery to prevent any electrical shorts during the repair (if needed).

2. Remove Door Panel

Using a flat screwdriver or pry tool, gently pry off any trim pieces surrounding the door panel to avoid damage.
Remove screws securing the door panel (typically located around the edges and behind the handle).
Carefully pull the door panel away from the door frame, starting from the bottom and working your way up to disengage the clips.

3. Inspect Window Motor and Wiring

Tools Required: Multimeter
Check the window motor connector for loose or damaged wiring.
Use a multimeter to test for power at the window motor connector when the switch is pressed.
- If no power is detected, trace the wiring back to the switch and check for continuity.

4. Replace Window Motor (if necessary)

If the window motor is confirmed to be faulty:
- Disconnect the motor connector.
- Remove any screws or bolts securing the motor to the door frame.
- Install the new motor by reversing the removal process, ensuring all connections are secure.

5. Reassemble Door Panel

Reattach the door panel by aligning it with the door frame and pressing it into place to engage the clips.
Replace any screws previously removed, tightening to manufacturer specifications.
Reinstall trim pieces.

6. Reconnect Battery and Test

Reconnect the 12V battery.
Test the power window operation from both the driver’s master switch and the individual window switch.
