Just wanted to let those know I found the fix. There were several people with similar problems.
My passenger side window would go down, but would not roll back up with either set of controls. A new motor did not fix the problem.
I ended up ordering a new switch. (I have the style that each switch pulls off the panel and has metal prongs on the bottom. From what I understand, only the early 94s have this type). I put the new switch on the passenger side, but it did not work. I tried the switch on the driver side - and voila, the window worked.
It turned out that the driver side controls for the passenger window were shot. The new switch works perfectly.
i wish mine was that simple.. my passenger window will only go up with the passenger control... i know my switches are all good (i've swapped them around to all positions).. so i need to tackle a freekin wiring problem.
