This is fairly simple once you know the trick. The crank handle It is held onto the window regulator shaft by a keeper that snaps onto the back part of the handle. they make a special tool to remove the clip, but sometimes can be done with a flathead screwdriver.
Push the plastic door panel back away from the crank you should be able to see the keeper snapped over the plastic part of the crank that goes onto the shaft. The keeper is sort of a circular spring with an opening. If you don't have the window crank tool, find a flat head screw driver that will part the opening in the spring far enough to slide it off. The crank handle pulls straight off.
