Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, and pliers.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Replace Blown Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse panel cover and identify the power window fuse using the diagram on the cover.
Use pliers to pull out the blown fuse and replace it with a new fuse of the same amperage.
Reinstall the fuse panel cover and reconnect the negative battery terminal.

3. Test Power Window Switches

If the fuse is intact, access the power window switch assembly.
Use a multimeter to test for continuity on each switch.
If a switch is found to be defective, remove the switch by unscrewing it from the door panel.
Install the new switch by reversing the removal process.

4. Inspect and Replace Window Motor (if necessary)

If the switches are functional, remove the door panel using a screwdriver and trim removal tool.
Disconnect the wiring harness connected to the window motor.
Test the window motor directly with a power source to determine if it operates.
If the motor is faulty, unbolt it from the door and replace it with a new unit, ensuring all connections are secure and the motor is aligned properly.
