I understand. There is not a way to check this manually because if you use a test light then you are just finding out if there is power getting to the motor.
However, you already know that it is because you can hear it engaging. The problem is, it is not moving the door and the grinding that you hear is the motor gear slipping in the track.
So, if you want to do more testing, remove the door panel and lay inside the vehicle and watch the operation of the track and motor and I am sure you will see it slipping.
This means you need to remove the motor and inspect the track and gear to see which is worn and normally it is the motor.
