on my 86 gt vert drivers side window, the windows goes down fine, but not up. it just makes a clicking noise. if i pull it up and use the switch at the same time it will go. put it up half way then just used the switch (no help from me) and the window falls a couple inches. push up on the switch again from there and it falls again. the window will stay where its at until i try to go up. going down it works fine.
