Okay, I was curious about the RAM because I know in my other car I can have the option to keep it on to help dehumidify and keep windows from fogging. I haven't really noticed any of the front windows fogging up but the rears do.Typically, the compressor will run in defrost mode. Not sure about other heating modes
I guess that would be a no then, kind of a shame they didn't allow both to be enabled.Auto will try to keep the temperature at what you have set, set it and forget it type of thing. The auto setting will determine if AC or heat is call for. An example would be if you a colder temp area and the heat is blowing and you travel south into a warmer area the AC will kick in if the cab temp goes above your set temp, not sure what the offset is. If you press the AC button you are taking it out of auto.
