Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked and turned off.
Disconnect the 12V battery to avoid electrical shock (if applicable).

2. Inspect and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the trunk.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers and inspect it for continuity.
- If blown, replace with a fuse of the same amperage rating.

3. Check and Repair Window Switches

Remove the trim around the window switch panel using a trim removal tool.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter for continuity when pressed.
- If faulty, replace the window switch with a new one.

4. Inspect and Test Window Motors

Remove the door panel to access the window motor.
- Use a socket set to remove screws securing the door panel.
Disconnect the motor's wiring harness.
Test the motor using a multimeter or by applying direct power from a 12V source.
- If the motor is non-functional, replace it with a new one.

5. Reassemble Components

Reattach the door panel and secure it with screws.
Reconnect the window switch and trim panel.
Reconnect the 12V battery.

6. Final Checks

Test the functionality of the power windows once everything is reassembled.
Clear any error codes through the vehicle's diagnostic interface if necessary.
