MAX A/C Not Available Below Freezing, but why?
Just learned that MAX A/C is not available when it’s below freezing out.
I often use this feature when leaving the gym – even in the winter – which I find preferable to opening the window, but never realized this. My car just had its battery replaced, and its HVAC control panel was replaced this past summer; I wonder if new programming is to account. Anyway, anyone know the reason why this feature is disabled below freezing? Thanks. |

Maybe if it's below 0 deg C then it's to protect the evaporator from damage?

Both protection from icing and the evaporator working temperature. It will be something in the range of 2 - 8C, with a default sensor value of -2C. Quote:
