Just started using the heater in my new 2016 Encore. After car is warmed up I turn on fan and adjust the temp knob. Nine times out of ten the A/C comes on when the fan is initiated. OK, so turn off A/C and continue. Then when parking car in garage, I turn the fan off before exiting so cold air doesn't blow in the morning. Next morning after warm up I again turn on fan but the A/C again comes on, even though I turned the vehicle off with heater on. Am I missing something? Why does A/C come on sporactically when vehicle was left with heater on, not A/C?
