Solution

1. Preparation

Tools Required: Multimeter, socket set, flathead screwdriver, Phillips screwdriver, wire connectors, electrical tape.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Fuse Replacement

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse for the power windows (refer to the owner's manual for the exact location).
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.

3. Switch Replacement

If the fuse is intact, proceed to remove the door panel:
- Use a flathead screwdriver to carefully pry off any trim pieces.
- Unscrew the screws securing the door panel.
- Detach the door panel by pulling it away gently to avoid breaking the clips.
Disconnect the wiring harness from the window switch.
Replace the switch if it is found faulty.

4. Motor and Regulator Inspection/Replacement

If switches are functional but windows still do not operate:
- Access the window motor by removing the inner door panel.
- Test the motor directly with a 12V supply; if it does not operate, it may need replacement.
- Remove the window regulator assembly if necessary to replace the motor.
Clean any debris from the regulator and lubricate moving parts to ensure smooth operation.

5. Reassembly

Reattach the window regulator and motor, ensuring all screws are tightened to the manufacturer's specifications.
Reconnect the door panel and replace any trim pieces.
Reconnect the negative battery terminal.
