a very basic check is to turn on the ignition and watch the ignition light whilst pressing the window button. If it dims slightly the motor is drawing power so the problem is either the motor is not working or something is broken on the mechanical part of the regulator inside the door. Then you will have to remove thr trim on the door to investigate
