Can you hear it trying to go up? What about down, can you hear it? If no audible noises your gonna have to take the door panel off and check at the window motor for power and ground when tryin to operate window, the terminal voltage will switch one way for up one way for down, but check and make sure you have power and groung both ways. If you do and the window doesnt move you have a faulty window motor. This might be one that comes bought as one unit, motor and regulator together
