Pontiac G6 Heating/Cooling
I turn on my car with both knobs on auto and the Air Conditioning light goes on. Now as far as I know most people aren't turning on the AC in the winter, also you tend to get worse gas mileage with this on. So I always turn it off.
Now it says in the manual the air conditioning compressor runs when the outside temperature is over at 40 degree F. Why would I want the AC on when its 40, maybe if its 80 or higher.
It also states when the air conditioning is selected or in AUTO mode, the system runs the air conditioning automatically to cool and dehumidify the air entering the vehicle, Again, if its cold outside why would anyone want the AC on it.
