Gotta love GM!

When my 99' Pontiac Grand Prix GTP was given to me I was aware it was sitting for a while. Shortly after registering it I found out that the rear passenger window wouldn't roll up!... But to make the situation even sweeter I realized the damn door can't lock either! I can't even move the lock by hand... Anyone have suggestions or advice? The window is currently down and I don't want to have to force it up. And with it being down theres pretty much no way of replacing the motor or track because its behind the window, is there a secret way in getting these windows up manually?

Help me get the trashbag outta my window! haha

Thanks!
