Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical shorts.
Ensure the vehicle is in a secure location, with adequate lighting.

2. Inspect and Test Window Switch

Remove the door panel using a socket set to access the window switch.
Disconnect the window switch connector.
Use a multimeter to test for continuity in the switch.
- If the switch is faulty, replace it with a new one.

3. Check the Window Motor and Regulator

If the switch is functioning, reconnect it and apply power directly to the window motor.
- If the motor operates, the regulator may be faulty and needs replacement.
- If the motor does not operate, replace the window motor.

4. Examine Wiring and Fuses

Inspect the wiring harness for frays, corrosion, or loose connections.
Replace any damaged wires or connectors.
Check the fuse box for the window circuit and replace any blown fuses.

5. Reassemble and Test

Reconnect the window switch and test the system.
Reattach the door panel securely.
Reconnect the battery and conduct a final test of the windows.
