Safety Warnings: Disconnect the battery before working on electrical systems.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use the fuse diagram to identify the power window fuse.
Remove the fuse and check for continuity with a multimeter.
If blown, replace it with a fuse of the same amperage rating.

3. Inspect and Repair Wiring Connections

Remove the door panel using a Torx screwdriver.
Carefully detach any clips holding the panel in place.
Once the panel is removed, visually inspect the wiring harness for wear or disconnection.
Repair any damaged wires by splicing in new wire or using electrical tape for minor issues.

4. Test and Replace the Window Switch

Using a multimeter, test for continuity on the window switch.
If the switch is faulty, remove it from the door panel.
Replace with a new switch ensuring proper connection to the wiring harness.

5. Check and Replace Window Motor (if necessary)

If the switches are functional but windows do not operate, test the window motor.
Disconnect the motor and apply direct power to check for movement.
If the motor does not respond, replace it with a new component.
