Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set), and a replacement fuse if needed.
Ensure the vehicle is parked safely and powered off.

2. Inspect and Replace Fuse

Locate Fuse Box: Access the fuse box, typically found under the dashboard or in the trunk area.
Check Fuses: Identify the fuses related to the power windows. Use the vehicle’s manual for the correct fuse locations.
Replace Blown Fuses: If any fuses are blown, remove them using fuse pullers and replace them with new fuses of the same amperage.

3. Test Window Motor

Access Window Motor: Remove the door panel by unscrewing screws and gently prying it away from the frame.
Disconnect Motor: Safely disconnect the window motor from the wiring harness.
Direct Power Test: Using a multimeter, apply direct power from a battery to the motor to see if it responds. If it does, the motor is functional.

4. Inspect Window Switch

Remove Switch Panel: Carefully pry off the switch panel using a trim removal tool.
Test Continuity: With a multimeter, check the switch for continuity. If there is no continuity, replace the switch.

5. Reassemble

Reattach All Components: Once repairs are made, reattach the window motor and ensure all electrical connections are secure.
Reinstall Door Panel: Carefully align and snap the door panel back into place. Reinsert screws to secure it.
