Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, screwdrivers, replacement window regulator or motor (if needed).
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace the Fuse

Locate the fuse box in the vehicle (typically under the dashboard or in the engine compartment).
Remove the cover and find the power window fuse. Use a fuse puller or pliers.
Check the fuse for continuity using a multimeter. If blown, replace it with one of the same amperage.

3. Test and Replace the Window Switch

Remove the door panel to access the window switch.
Disconnect the electrical connector from the switch.
Test the switch using a multimeter to ensure it is functioning. If defective, replace it with a new switch.

4. Inspect and Replace the Window Motor

Remove the door panel carefully to access the window motor and regulator assembly.
Disconnect the motor's electrical connector.
Test the motor for functionality by connecting it directly to a power source.
If the motor is non-functional, remove the screws securing it and detach it from the regulator. Replace with a new motor.
If replacing the regulator, remove the old regulator and install the new one following the manufacturer’s instructions.

5. Reassemble and Test

Reconnect all electrical connectors and ensure all components are securely mounted.
Reinstall the door panel, making sure not to pinch any wires.
Reconnect the negative battery terminal.
Test the power window operation to ensure proper functionality.
