i own a 2001 s4 and my front drivers side window is stuck down and wont go up....is this a motor issue? and if so, what kind of motor do i need?? is there a differenct in say the 2001 and 2001.5 motors? and can i just take one from an a4? any specific year?

 

does the widow motor still run, but the window doesnt go up?
