Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety during the repair.
Tools required: Screwdriver set, multimeter, socket set, and trim removal tools.

2. Replace the Fuse

Locate the fuse box and identify the power window fuse (refer to the owner's manual for the exact location).
Remove the faulty fuse and replace it with a new one of the same amperage.

3. Inspect and Replace the Window Switch

Remove the trim panel around the window switch using trim removal tools.
Disconnect the switch from the wiring harness.
Test the switch with a multimeter to confirm continuity.
If faulty, install a new window switch by connecting it to the wiring harness and securing it in place.

4. Test and Replace the Window Motor

If the switch is functional, access the window motor by removing the door panel.
Disconnect the motor from the wiring harness and test it with a multimeter for proper voltage.
If the motor is defective, remove it by unscrewing the mounting bolts, replace it with a new motor, and reassemble the door panel.

5. Reassemble and Test

After all repairs, reattach the door panel securely.
Reconnect the vehicle's battery.
Test all windows to ensure they operate correctly.
