How do you remove the window crank on a 1999 Chevy Cavalier in order to remove the door panel to fix a rear passenger door that does not open?

All you need is a paint can opener. Under the window crank there is a horseshoe shaped pin and you just need to snag it and pull it out.

Put down the window first and do the above. Then after romoving all the screws in the door panel lift up on it until it pops off.
