Jonny, I checked out the thread you linked, and have to say how impressed I am with your post #7. I went a different way, disconnecting all of the lever cables so that i could pull the HVAC control assembly and work on it. Your approach -- removing the switch without removing the HVAC assembly -- was very nice, and the write-up was terrific.

I will say, though, having gone to all that work (either way), I would just spend the $50 or so (at Autozone) for a new switch, rather than trying to repair the old one or put in a used one.
