power window

Hi
I have 2000 Crown Vic. 4 months ago I replace the front left motor of my power window, the window stop work 2 months after that, now my front right window stop working too, a friend of mine told me that maybe some kind o control module and not the motor or regulator. My question is what crontol module is that?
Thanks

could be the master window switch on the drivers side gone bad.i believe the right side gets power from the master switch on the drivers door.either get a new drivers side master or go get one from junkyard.then both sides should work.
