Windows problem..
 

OK... Here is another question.. I drove my car down to the beach today for a meeting.. Car ran well.. I have had problems with the windows in the past. One window would stop then the other would not work.. Anyway, today one of the windows stopped working.. I have replaced the relay, twice. I have checked the fuse.. I have changed the switches ( 1983 944 N/A) I cant figure this out.. Any ideas??

check for power at the window motor, maybe the motor has a bad spot for the brushes.

Alan has a very good suggestion. I had the same issue last year and after messing around with everything else, I removed the regulator motor and thoroughly cleaned the brush contacts (and all other internal components). The shaft bearing/bushings were re-lubed and it came back to life!. It may be something to look into...
