Hello all. I'm in the process of trying to take my back driver side door apart and can't seem to figure very much out. I've gotten the panel off but not much else. The main problem I'm encountering is a black plastic panel inside the door, which blocks access to the outside door handle assembly. It appears to be held in place by some sort of clip at the top of the panel. It would also prevent the removal of the door lock assembly, so if there is anyone out there that has experience here I would much appreciate some advice. I've attached a photo of the panel and the clip that holds it in place. Thanks.
