Solution

1. Preparation

Gather necessary tools: flathead screwdriver, Torx screwdriver set, and a multimeter.
Ensure the vehicle is parked and powered off. Disconnect the 12V battery for safety.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box (under the dashboard or behind the driver's side panel).
Identify the power window fuse using the diagram in the owner’s manual.
Use the fuse puller to remove the fuse and inspect it. If blown, replace it with a fuse of the same amperage rating.

3. Check Wiring and Connections

Tools Required: Torx screwdriver set
Remove the door panel by unscrewing the Torx screws and gently prying off the panel using a flathead screwdriver.
Inspect the wiring harness for any visible damage or disconnections, especially at the door's hinge area.
Reconnect any loose wires and repair any damaged wiring with electrical tape or connectors.

4. Test and Replace Window Motor (if needed)

Tools Required: Multimeter
Reconnect the battery and use a multimeter to test the window motor for continuity.
If the motor does not have continuity, it will need to be replaced.
Remove the motor by unscrewing it from its mounting location and disconnecting the wiring harness.
Install the new motor by reversing the removal process.

5. Reassemble Door Panel

Reinstall the door panel by aligning it properly and securing it with the Torx screws. Ensure all clips are engaged.
Reconnect the battery and test the windows to ensure proper operation.
