I was driving down the road and all of a sudden my a/c went from auto to econ and won't go back to auto, I do not have any system messages on the dic, so where do I start? it is hot here..... if it was low on refrigerant, wouldn't the dic say something?

Check the DTC's. There should be one for low refrigerant.
