2001 Jeep Cherokee power window door lock malfunction?

Hello,
I can raise and lower all windows from the driver's controls but cannot rais or lower any passenger windows from their own control. I removed the driver's door panel and took out the switch assembly thinking that the window lock swithc was malfunctioning. I noticed two broken solder joints by that switch and resoldered them. This did not do the trick. If bypassing the switch or closing the circuit would do it I would but now I am not shure that that is the problem.
