If the connection is loose, reconnect it securely.
If the motor appears faulty, proceed to replace it.

5. Replace Window Motor (if necessary)

Disconnect the motor wiring harness.
Remove the motor mounting screws.
Install the new motor, ensuring it is securely fastened.
Reconnect the wiring harness.
