Solution

1. Preparation

Gather tools: screwdriver set, multimeter, wire connectors, and a replacement fuse if necessary.
Ensure the vehicle is turned off and keys are removed from the ignition.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power window fuse (refer to the fuse diagram on the cover).
Remove the fuse and inspect it; replace if blown.
Reinstall the new fuse and test the power windows.

3. Inspect and Repair Wiring

Detach the door panel using a screwdriver to access the wiring harness.
Check for any frayed wires or loose connections within the harness.
Repair or replace damaged wiring as necessary using wire connectors.

4. Test and Replace Window Motor

Disconnect the window motor connector.
Use a multimeter to check for voltage at the motor plug while pressing the window switch.
If no voltage is present, further investigate the switch or wiring.
If voltage is present but the motor does not operate, replace the window motor:
- Remove the window from the regulator assembly as needed.
- Unscrew and detach the motor from the regulator.
- Install the new motor by reversing the removal steps.

5. Reassemble and Test

Reattach the door panel carefully, ensuring all clips are secured.
Test the power windows to confirm proper operation.
