@PLP - how are you making out? I fixed the passenger door today. Replaced the 2 micro switches in the door handles and the door latch that has the 3rd micro switch. The door latch mechanism that was in there had a short and actually blew a fuse as I was removing it. Car is now 100%. I actually also had a issue with the spoiler. I’ve seen a lot of videos of people replacing the entire unit but not restoring. After 20+ years the grease isn’t any more. I disassembled that, re- greased it and that is now working perfectly too.
Great news
Where did you get the microswitces? I need to tackle the same issue on the passenger side door as well.
I should say that our host sells the micro switches too. Look at the beginning of this tread for the links (but make sure the door latch is compatible with your car).
