2001 Nissan Sentra Door Panel

I have a four door that has a bad window drive motor on the passenger side front door. I went to remove the door panel and am having trouble. There is a screw at the bottom of the door panel and a plastic rivet type screw on the upper forward part of the panel. I removed the trim ring around the door handle. There is another screw under the plastic panel that holds the window switch and door lock switch. After removing that and popping the panel loose from the bottom to the top there is still something holding the panel in the center behind the arm rest. I have looked all over the arm rest and I can see no way to get to it. Anyone have any information on this, I would greatly appreciate you knowledge.

 

There's another screw behind the armrest, pop the armrest up from the rear and slide it out.

When it's all out and, put the window switch back on, key on engine off, press and hold the down button and give a window motor a whack and see if it's "loosing up".
