I don't know if the diagram will help or not? I know what you mean about remembering, I'll be 65 in a couple of months. I was trying to take an old computer apart. I had done it before in the past, just couldn't remember at the moment? It finally dawned on me, I just shook my head and went on. Lol

Youll need a doorpanal tool. Remove the 2 screws behind the pull handle. Then remove the switch plate and any screws holding the armrest on.U may have to remove lights and remove hidden screws remove the screw behind the inside handle and any screw you see then use the tool pry it off.
