Solution

1. Preparation

Tools Required:
- OBD-II scanner (if needed for diagnostics)
- Multimeter
- Screwdriver set
- Trim removal tool
Disconnect the negative battery cable to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or hood.
Use the fuse diagram to identify the power window fuse.
Remove the fuse and inspect it for continuity; replace if blown.
Reconnect the battery and test the windows.

3. Check and Replace the Power Window Switch

Remove the trim panel around the power window switch using a trim removal tool.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity when pressed.
If faulty, replace the switch with a new one.
Reassemble the trim panel and reconnect the battery.

4. Test and Replace the Power Window Motor

Remove the door panel to access the window motor.
Disconnect the motor wiring harness.
Use a multimeter to check for power at the motor connector when the switch is activated.
If no power is present, trace back to the switch; if power is present, replace the window motor.
Reinstall the new motor and door panel.

5. Inspect Wiring Harness

With the door panel removed, visually inspect the wiring harness for damage or fraying.
Repair any damaged wiring with solder or electrical tape.
Ensure all connections are secure before reassembling the door panel.
