Thanks to all of you for the help. Had the door panel off but not unplugged from anything three times. Not until the last time I took it off completely did I find the rattle was in the door, not the panel. Turns out it was the black box that the cables for unlocking and opening attach to, and where it has a plug through the door to plug the wires into. The little piece of cheap foam they use was out of alignment and was making a noise sort of like when scotch tape is pulled off and on at 50 times a minute. Anyway case solved. And taking the door panel offand on is easier then I thought.
