Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the vehicle's battery for safety to avoid electrical shock or damage.

2. Inspect and Replace Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Refer to the vehicle’s manual to identify the specific fuse for the power windows.
Remove the fuse and inspect it for continuity using a multimeter.
- If the fuse is blown, replace it with a new fuse of the same amperage.

3. Check and Replace Window Switch

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the wiring harness from the window switch.
Test the switch using a multimeter for continuity. If it’s faulty, replace it with a new switch.
Reconnect the wiring harness and reassemble the door panel.

4. Inspect and Replace Window Motor

If the switch is functional but the window still doesn’t operate, proceed to the window motor.
Disconnect the wiring harness from the window motor.
Use a multimeter to check for voltage at the motor terminal when the switch is activated.
- If there is power but the motor does not operate, replace the window motor.
Install the new window motor, reconnect the wiring harness, and reassemble the door panel.
