Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, and wire connectors.
Ensure the vehicle is parked and turned off, with the keys removed from the ignition.

2. Inspect and Replace Fuse

Locate the fuse box: Refer to the owner's manual for the exact location of the power window fuse.
Check the fuse: Remove the power window fuse and inspect it. If it is blown, replace it with a new fuse of the same amperage.
Re-test the windows: Try operating the windows again after replacing the fuse.

3. Test Power Window Switches

Remove the door panel: Use a screwdriver to remove screws securing the door panel and gently pry it off to access the switches.
Disconnect the switch: Unplug the window switch connector from the harness.
Check continuity: Use a multimeter to test for continuity across the switch terminals. If faulty, replace the switch.

4. Inspect Wiring and Connectors

Examine the door harness: Look for any frayed wires or loose connections in the wiring harness.
Repair or replace damaged sections: Use solder or wire connectors to repair any damaged wiring.

5. Test Power Window Motor

Access the window motor: If the switch and wiring are functional, remove the window regulator assembly to access the motor.
Apply direct voltage: Connect the motor directly to the battery to see if it operates. If it does not, replace the power window motor.

6. Check Window Regulator

Inspect the regulator: Ensure that the regulator is not bent or obstructed. If damaged, replace the window regulator assembly.
Reassemble the components: Reinstall the motor and regulator, then reattach the door panel.
