Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Check Fuses

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 on the cover.
Use a fuse puller to remove the fuse and inspect it for continuity. Replace if blown.

3. Inspect and Test Window Switch

Remove the door panel using a trim removal tool to access the window switch.
Disconnect the switch connector.
Use a multimeter to check for continuity between the switch terminals when pressed. Replace if faulty.

4. Check Wiring and Connectors

Visually inspect the wiring harness leading to the window motor for any signs of wear or damage.
Ensure all connectors are securely fastened and free of corrosion.

5. Test Window Motor Operation

If the switch is functional, test the window motor by removing it from the door.
Connect the motor directly to a 12V power source using jumper wires. The motor should operate; if not, replace the motor.

6. Reassemble and Test

If all components are functioning, reinstall the window motor and door panel.
Reconnect the negative battery terminal.
Test all power windows to ensure they operate correctly.
