Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Ensure you have ample working space around the vehicle doors.

2. Inspect Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the fuse for the power windows (refer to the owner's manual for the exact fuse location).
Inspect the fuse for continuity using a multimeter; replace if blown.

3. Test Power Window Switch

Remove the switch panel from the door using a trim removal tool.
Disconnect the electrical connector from the switch.
Use a multimeter to check for continuity across the switch terminals when pressed.
If faulty, replace the switch with a new one.

4. Check Wiring and Connections

Inspect the wiring harness that runs through the door for any signs of wear or damage.
Ensure all connectors are firmly seated and free from corrosion.
Repair or replace any damaged wires as necessary.

5. Test Power Window Motor

Remove the door panel to access the power window motor.
Disconnect the motor's electrical connector.
Use a multimeter to test for voltage at the motor connector when the switch is pressed.
If voltage is present but the motor does not operate, replace the power window motor.

6. Reassemble Components

Reinstall the door panel and switch panel in reverse order of removal.
Reconnect the negative battery terminal.
Ensure all screws and clips are secure.
