Solution

1. Preparation

Gather tools: Multimeter, screwdrivers, socket set, OBD-II scanner, and possibly a new power window switch or motor.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Inspect and Replace Fuses

Locate the fuse box; refer to the owner’s manual for the specific location.
Remove the cover and visually inspect the power window fuse.
If blown, replace it with a fuse of the same amperage (usually 30A for power windows).

3. Test the Power Window Switches

Remove the switch panel using a trim removal tool.
Disconnect the switch connector and use a multimeter to test for continuity.
If there's no continuity, replace the power window switch.

4. Check the Window Motor

Remove the door panel to access the window motor.
Disconnect the motor's electrical connector.
Using jumper wires, connect the motor directly to the battery to check for functionality.
If the motor does not work, replace it.

5. Inspect Wiring and Connectors

While the door panel is off, visually inspect the wiring harness for any frays or damage.
Repair any damaged wires with solder and heat shrink tubing or replace the harness as necessary.

6. Reassemble and Secure Components

Reattach the door panel carefully, ensuring all clips and screws are secured.
Test the windows again to confirm proper operation.
