Solution

1. Preparation

Gather necessary tools:
- Screwdriver set
- Multimeter
- Trim removal tool
- Torque wrench
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery cable for safety.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram.
Pull the fuse using pliers or a fuse puller and inspect it.
- If blown, replace it with a new fuse of the same amperage.
- If not blown, proceed to the next step.

3. Test and Replace the Window Switch

Use a trim removal tool to carefully detach the door panel.
Disconnect the window switch connector.
With a multimeter, test the switch for continuity when pressed.
- If faulty, replace the switch with a new one.
- If functioning, continue to the next step.

4. Test and Replace the Window Motor

Remove the door panel completely by unscrewing any remaining screws and carefully prying it off.
Disconnect the window motor connector.
Test the motor with a multimeter to check for voltage when the switch is activated.
- If there is power but the motor does not operate, replace the window motor.
- If no power, check the wiring harness and connections.

5. Reassemble the Door

After repairs, reattach the door panel by aligning it properly and securing all screws.
Reconnect the window switch and any other connectors removed during the process.
Reconnect the negative battery cable.
