Solution

1. Preparation

Gather tools: Socket set, multimeter, OBD-II scanner, screwdrivers, and a flashlight.
Ensure the vehicle is parked on a level surface with the ignition turned off.

2. Fuse Inspection and Replacement

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram.
Use a multimeter to check for continuity in the fuse.
- If the fuse is blown, replace it with one of the same amperage rating (usually 30A).
- Recheck window operation after replacement.

3. Switch and Wiring Inspection

Remove the door panel using a screwdriver and trim tools to access the window switch assembly.
Disconnect the window switch connector and use the multimeter to check for voltage at the switch terminals when the switch is activated.
- If no voltage is present, the issue may be with the wiring harness or a faulty switch.
Inspect all visible wiring for frays or breaks, repairing or replacing as necessary.

4. Window Motor Testing

If the switches are functional, locate the window motor in the door assembly.
Disconnect the motor connector and test for power using the multimeter.
- If voltage is present but the motor does not operate, replace the window motor.
- If no voltage is present, trace the wiring back to the switch for further issues.

5. Reassembly

Once repairs are completed, ensure all connections are secure.
Reattach the door panel, ensuring all clips and screws are properly fastened.
Test all windows to confirm proper operation before completing the job.
