window issue 83 300td
 

I just purchased a 1983 300td wagon, im in a somewhat restoration stage with it now.
when i got it all the windows rolled down and up with no problems. For reasons unknown to me, the passenger front is in the down position and will not roll up, and the driver side rear is up and will not roll down. I have taken out the switches and put some working switches in, and still the same thing, no up on passenger, no down on rear driver.?? if it is not the switches, where does that leave me? am i totally missing something here?
any suggestions?
