Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the battery to avoid electrical shock.

2. Check and Replace Fuses

Locate the fuse box (typically under the dashboard or hood).
Remove the power window fuse (refer to the owner's manual for the specific fuse location).
Inspect the fuse for any signs of damage; replace if necessary with a fuse of the same amperage.
Reconnect the battery and test the window operation.

3. Inspect and Replace Switches

If the fuse is intact, remove the switch panel using a trim removal tool.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter for continuity.
If faulty, replace the switch with a new one and reinstall the panel.

4. Check Window Motor and Wiring

Remove the door panel using a socket set and trim removal tools.
Disconnect the window motor connector and test for voltage while pressing the window switch.
If there is voltage, the motor may be faulty; remove the motor and replace it.
If there is no voltage, inspect the wiring for breaks or corrosion and repair as necessary.

5. Reassemble and Test

Reinstall the door panel and ensure all clips are secured.
Reconnect the battery.
Test all windows to confirm proper operation.
