Solution

1. Preparation

Gather tools: multimeter, socket set, screwdrivers, and a replacement fuse if needed.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Fuse Inspection

Locate the fuse box (refer to the owner's manual for exact location).
Remove the cover and find the fuse associated with the power windows.
Inspect the fuse for continuity using a multimeter; replace if blown.

3. Window Switch Testing

Remove the window switch panel using a screwdriver.
Disconnect the switch harness and test for continuity on the switch terminals.
If defective, replace the switch with a new one.

4. Motor and Regulator Check

If the switch is functional, access the window motor by removing the door panel.
Disconnect the motor's connector and apply 12V directly to the motor terminals.
If the motor operates, inspect the regulator for wear. If the regulator is damaged, replace it.

5. Reassembly and Testing

Reinstall the door panel securely once repairs are complete.
Reconnect the battery if it was disconnected.
Test the power windows to ensure they now function correctly.
