The vent window assembly needs to come out also (bunch of hidden screws behind weather stripping 3 on side & one on top if I recall correctly AND the main one on the door body). The window is held to the channel that it rides up and down on with a clipped in piece of plastic roller ($2-3 and worth replacing). Unclip and pull the lift arm out, then pull the glass up and out of the window opening. The window should come out with the one channel still attached.
