Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle’s battery to ensure safety during the repair.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use the fuse diagram to find the power window fuse (usually labeled).
Remove the fuse using a fuse puller and inspect it for continuity. Replace if blown.

3. Test and Replace Window Switch

Remove the door panel to access the window switch.
- Use a trim removal tool to carefully pry off the panel.
- Unscrew any screws holding the panel in place.
Disconnect the window switch connector and test it with a multimeter for continuity.
If faulty, replace the switch with a new one.

4. Inspect and Test Window Motor

Access the window motor by removing the door panel (if not already done).
Disconnect the motor connector and apply direct battery voltage (positive to red wire, negative to black wire).
If the motor does not operate, replace it with a new motor.

5. Reassemble and Test

Reattach the door panel and secure all screws.
Reconnect the vehicle's battery.
Test the power windows to ensure they are functioning correctly.
