Before I change the blower regulator, I got a email from a guy that had the exact problem and he recommended changing the evaporator temp sensor. It' came today <$45.00 delivered. Now I have to figure out how to remove the panel under the dash. It looks like 2 screws and a large plastic keeper of some sort. Anyone ever removed this? The sensor simply plugs in to the system but getting to it may be a big headache. Regards, Rick.
