I have the atc in my concorde. Lately when the heat is set between 70-73f it will at randomly just start blowing colder air. Once I turn it up past 74 the heat comes back, it stays this way til I restart the car then the heat works again. I ran the calibration on it, it gave no code. Any ideas what this might be?
