I have a similiar problem. My driver's side doesn't go up and down by itself, rather it goes up only in 1" increments. I heard it was something with a magnet being off alignment inside the door panel near the switch, or something like that. I'll see if I can find where I saw the DIY on it.
By the way, Jason, your car is very nice! Can i ask what degree of window tint you have? I need to get it.
