Used my heater for the 1st time the other morning. I have the environment set to "Auto." I notice the A/C gets turn on, even though I set the temp to 80.
Why does the A/C get turned on in automatic mode when heating? I know cars will turn on a/c for defrost to eliminate humidity, but it seems odd that it should be on for heat? I turned it off and verified that the air coming out remained warm, but pressing the auto button (or shutting off an starting the truck) result in it going back on. I guess it's on purpose, but wondering why?
