Solution

1. Preparation

Gather necessary tools: socket set, multimeter, OBD-II scanner, and a wiring diagram.
Ensure the vehicle is in a safe position and the ignition is off.

2. Check and Replace the Fuse

Locate the fuse box using the vehicle’s manual.
Identify the fuse associated with the electric windows.
Remove the fuse using a fuse puller and inspect it for continuity.
- If blown, replace it with a new fuse of the same amperage.

3. Test the Window Motor

Disconnect the window motor wiring harness.
Using a multimeter, check for voltage at the harness when the window switch is activated.
- If voltage is present, the motor may need replacement.
If no voltage is present, inspect the wiring for continuity.

4. Replace the Window Motor (if necessary)

Remove the door panel using a socket set to access the window motor.
Disconnect the motor from the window regulator.
Install the new motor in reverse order of removal, ensuring it is securely fastened.
Reconnect the window motor wiring harness.

5. Reassemble and Test

Reattach the door panel and secure it with screws.
Test the window operation from both the driver and passenger switches.
Ensure all functions are restored before finalizing the process.
