Try having an assistant open the door and place their palms on each side of the glass like a sandwich and push down while operating the switch. Mine used to to this after not being used for a while and I think the glass sticks to the weatherstrip after a while. Slaming the door will sometimes free them up but the hand sandwich technique seems to work better. BTW they stopped sticking altogether when I got my Weathertech inside-the-track window visors since they now contact the outside of the glass instead of the weatherstrip. You can also slide a plastic putty knife between the weatherstrip and glass all the way around the window inside and outside before operating the switch and see if that works.I use the "wickerchargerrt" technique on my Durango. It's usually the rear windows also. Not sure if it helps, but if I have an "assistant", I have them hold down the master switch while I slam.
Now they are both stuck beyond slamming so I guess it is time to get out the test light.
Power windows suck, always start with the simplest thing 1st. Check the fuse.
My 94 Camaro, the passenger window wouldn't roll up or down unless I pressed the button on the drivers side at the same time. If I was alone in my car, I would have to hold the button on the drivers side while leaning over to press the passenger doors button. Something to do with the switch, I don't remember exactly because I hated that car (even though it was beautiful) and the dealership. I've basically suppressed the memory as much as I can. That car was a nightmare.
