Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and a replacement fuse (if needed).
Disconnect the battery to avoid electrical shorts while working on the vehicle.

2. Check Window Lock Switch

Locate the window lock switch on the driver’s side door.
Ensure the switch is in the "off" position to allow window operation.

3. Inspect and Replace Power Window Fuse

Locate the fuse box under the dashboard or hood.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using pliers and inspect it for continuity; replace if blown.
Reinstall the fuse and reconnect the battery.

4. Test Power Window Switch

Remove the switch panel from the driver's door using a flathead screwdriver.
Disconnect the electrical connector from the power window switch.
Use a multimeter to check for continuity across the switch terminals when pressed.
If there is no continuity, replace the power window switch.

5. Inspect Wiring and Connectors

Visually inspect wiring harnesses for fraying, corrosion, or disconnection.
Repair any damaged wires with electrical tape or by replacing the harness.
Ensure connectors are clean and securely attached.

6. Test Window Motor

Remove the door panel to access the window motor.
Disconnect the window motor connector.
Using a multimeter, test the motor for continuity.
If faulty, replace the window motor with a new one.
