DZ's description made no sense to me at all.
Taking off the door panel is easy enough; remove the screws along the edges, remove the pull handle, remove the window crank (pop out the clip on the back side.) Then pull it out to unsnap the clips, then lift it upwards and slide it away from the body. Easier to do than write. Peel off the plastic protector from the door.
As for the window -
Put the window all the way down.
Remove the guide channel from the the triangular plastic piece in the corner of the window opening.
Remove the screws from it and remove the triangular plastic piece.
Roll the window up about 1/4 of the way to get to the screws in the regulator arm.
Remove the screws that attach the regulator arm to the glass channel.
Lift the glass upward while tilting inward and remove it from the door.
