Power window on drivers side works and passenger side does not, why? on 1995 Chevrolet G Series Van (G20)

There are no strange noises, one side works fine and the other does not work at all.

you may have a window swtich issue. does window work with that side switch only or not at all. also poss window motor is seized up
Is there anything that i can do (outside of hitting the motor with a hammer) to unseize the window power motor?
