1990 Buick Skylark Power windows won't work

All four power windows do not work up or down...replaced window switch and have power to all 4 windows on the switch ......i unplugged drivers window from the switch and manually wired drivers window and it works fine...is there something like a computer or controller under the dash that the power is routed to from the window switch? I got my switch from a junkyard Car that just came in and the windows worked fine...
