Solution

1. Preparation

Gather tools and materials.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the power window fuse in the fuse box (refer to the owner's manual for the exact location).
Remove the fuse and inspect it for continuity.
If blown, replace it with a new fuse of the same rating.

3. Inspect and Repair Wiring

Examine the wiring harness connected to the power window switches and motors.
Look for frayed wires, corrosion, or loose connections.
Repair any damaged wires by splicing in new wire or replacing the harness entirely.

4. Test and Replace Power Window Switch

Remove the power window switch panel carefully.
Use a multimeter to test the switch for continuity when pressed.
If defective, replace the switch with a new one.

5. Inspect and Replace Window Motor

Remove the door panel to access the window motor.
Disconnect the motor's electrical connector and use a multimeter to test for power.
If there is power and the motor does not operate, remove and replace the window motor.
Reinstall the motor, ensuring it is properly aligned.

6. Reassemble Components

Reattach the door panel securely and test the window operation before final assembly.
Reconnect the battery.
