I'll have to give that a try, too. Is it possible that it's the switch? Possible the Blender module that has been mentioned in another thread?
It seems just a little unlikely that both the blower and the AC clutch would go at the same time. I get the impression that the thermostat for the climate controls isn't sending the appropriate singles for the heat and AC, as well as the blower fan speed dial receiving the signal to be active.
I don't want to go to a dealer...they are all crooks.
