After investigation, I found the black (ground?) wire to the ATC blower controller had corrosion. I wiggled it and powder came out and it worked again. Upon closer inspection, I saw discoloration from heat. I believe this controller and harness need to be replaced. (not bad for just an average "Joe" who didn't grow up around car mechanics). Controller has a part # and I was able to find a used one with attached harness for 1/2 price of new. I don't like the idea of a used part, but can't find a harness ANYWHERE, and this solution covers that ad possibly the controller as well for just 1/2 price.
