In any case, this was the job that made me smile the most. One of the easiest things I've done on the car, but what a difference it makes driving around here in Atlanta. Major annoyance, gone.

Just cleaned the pads as you suggest with a pencil eraser and a cotton swab dipped in isopropyl alcohol on my 95'. The Off and Auto as well as the Temperature toggle was not functioning. Now ALL work perfectly

Great write up with excellent photos
