It is hard to see from the information. It isn't clear. It appears your switch is connected to the door latch. Take some WD40 and spray really good inside where the red arrow is. Then you may need to pull the panel and clean the switch on the second pic. First please look at the side of the dash where the door meets the dash to make sure there isn't a plunger switch there. I just want to make sure since the wiring diagram says in the door.
