I need to remove a couple panels to get some work done in my car. One is the door panel. I popped the switch panel out and unscrewed the two screws behind there. I also popped the plug out of the front bottom, but it felt like something more then some clips were holding it in. What am I missing? The second one is the passenger side panel in the back. Does the bottom part of the back seat need to come out for it? If so, how does the back seat come out? TIA.
