Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and trim removal tools.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box: Refer to the owner's manual to find the specific fuse for power windows.
Remove the fuse: Use a fuse puller or pliers to carefully remove the fuse.
Check the fuse: If the filament is broken, replace it with a fuse of the same amperage.

3. Test and Replace Window Switch

Remove door panel: Use a trim removal tool to gently pry off the door panel and access the switch.
Disconnect the switch: Unplug the wiring harness from the window switch.
Test for continuity: Use a multimeter to check for continuity across the switch terminals when pressed.
Replace if faulty: If there is no continuity, replace the switch with a new one.

4. Inspect and Replace Window Motor

Access window motor: If the switch is functional, remove the door panel completely to access the motor.
Disconnect motor: Unplug the wiring harness from the window motor.
Test motor: Apply 12V directly to the motor terminals using jumper wires to see if it operates.
Replace if faulty: If the motor does not respond, remove it and install a new window motor.

5. Check Wiring and Window Regulator

Inspect wiring: Look for any visible damage or disconnections in the wire harness.
Examine the window regulator: If the motor is operational but the window does not move, the regulator may be damaged. Remove and replace it if necessary.
