Solution

1. Preparation

Gather tools: screwdriver set, multimeter, wire stripper/crimper, and a replacement fuse if needed.
Disconnect the vehicle battery to ensure safety during electrical work.

2. Check and Replace Fuses

Locate the fuse box and identify the fuse for the power windows using the diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse visually; if the wire inside is broken, replace it with a new fuse of the same amperage.

3. Inspect and Repair Wiring

Remove door panel using a screwdriver to access the window switch and wiring.
Check for any frayed or broken wires in the harness.
Repair any damaged wires using a wire stripper and crimper to reconnect them securely.

4. Test and Replace Window Motor

If the wiring is intact, test the window motor by connecting it directly to a power source (battery).
If the motor does not operate, remove the window motor from the door by unscrewing it.
Replace it with a new motor if faulty.

5. Reassemble Door Panel

Reattach the window switch and ensure all wiring is secured.
Reinstall the door panel and ensure all clips and screws are properly fastened.
