I just got a 94 3000gt sl a week ago. The car runs good and only needs minor things done (like new brake pads etc). I came home today and the driver side window wouldn't roll all the way back up. There's no out of the ordinary sound or sign of struggle either. The other window sounds the same but it goes up all the way. Before I go attempt to take the door off (which I have never done before and don't want to start now), is this a common problem on this car?

 

Common problem is electrical. the antenna seem to be the popular one.
