Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, basic socket set, and replacement fuse or switch as needed.
Disconnect the negative battery terminal to ensure safety while working on the electrical components.

2. Replace Blown Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse corresponding to the power windows (refer to the fuse box diagram).
Remove the blown fuse using a fuse puller or pliers.
Insert a new fuse of the same amperage rating (typically 20A for power windows).

3. Replace Power Window Switch (if faulty)

Remove the panel covering the power window switch by unscrewing or unclipping it.
Disconnect the wiring harness from the back of the switch.
Install the new power window switch by reconnecting the harness and securing the panel back in place.

4. Test Window Motor (if necessary)

Remove the door panel to access the window motor (typically involves removing screws and clips).
Disconnect the window motor connector.
Use a multimeter to check for voltage at the motor connector when the switch is activated.
If no voltage is present, check the wiring leading to the motor.
If voltage is present and the motor is non-functional, replace the window motor.
