I can only comment too, on my 84! I bought the whole window frame motor combo deal and my my pro mech. put it in and it makes a noise when operating on the drivers side (a bang sound @ mid cycle) which he said he could not adjust out of the mechanism (usually he does not give up easy) he too said it was a major pita working on it all and close quarters etc. The passenger side did work fine and no sounds going up and down. btw the bang is not too bad and it is not one that will harm the window or the frame device so we live with it and with plenty others that the old 84 makes even though it has only 53k miles on it and less then my ZR-1 @ 60k!!!
THIS 84 IS FOR SALE AT THE RIGHT PRICE!!!
