My outside door handle won't open the door on the passenger side. I would like to get in and replace it, but I can't figure out how to get the door panel off. I have a '93 del Sol Si. I have removed every screw and plastic pin that I could find, took the interior door handle off and I still can't budge the panel. What am I missing? Do I need a special tool?

Any replies would be greatly apreciated as my spare time runs out with the new year.
