Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, flathead screwdriver, and a panel removal tool.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fuse Inspection

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.
Pull the fuse using the fuse puller tool and inspect it for continuity. Replace it if blown.

3. Switch Testing

Remove the door panel using a flathead screwdriver and panel removal tool.
Disconnect the window switch connector and test for voltage with a multimeter while pressing the switch.
If there is voltage, the switch is functioning, and proceed to check the window motor.

4. Motor and Wiring Inspection

If the switch is functioning, locate the window motor behind the door panel.
Disconnect the motor connector and measure the voltage while activating the switch.
If voltage is present but the motor does not operate, the motor may need replacement.
Inspect the wiring harness for any signs of wear, fraying, or disconnections.

5. Motor Replacement

To replace the motor, remove the screws securing it to the door frame.
Disconnect the motor from the window regulator and install the new motor in reverse order.
Reconnect the wiring harness and reassemble the door panel.

6. Final Assembly

Reattach the door panel securely, ensuring all clips and screws are in place.
Reconnect the negative battery terminal and test the window operation.
