Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.
Tools Required: Socket set, multimeter, OBD-II scanner, wiring harness repair kit (if needed).

2. Check and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse for the power windows using the diagram on the fuse box cover.
Remove the fuse and inspect it visually for breakage; if broken, replace it with a fuse of the same amperage.
Recheck the functionality of the windows after replacing the fuse.

3. Inspect and Replace Power Window Switch

Remove the door panel using a socket set to access the power window switch.
Disconnect the switch connector and test it for continuity with a multimeter.
If faulty, replace the power window switch with a new one.
Reinstall the door panel after the switch replacement and test the window operation.

4. Test and Replace Window Motor (if necessary)

If the switch is functional, access the window motor by removing the door panel.
Disconnect the window motor connector and test it using a multimeter to check for proper voltage when the switch is pressed.
If the motor is not receiving power, inspect the wiring for damage.
If the motor is faulty, replace it with a new motor, ensuring to follow installation instructions.
Reassemble the door and test the window operation.
