 defrost in feet just a feet but the ac is not engaged it still stays really cold okay is the ac compressor on would be the first question no no if the ac compressor is not on then it's cold because you've got the temperature set too low not when it's 100 degrees out well then the ac compressor has to be on i know of no other way that the vehicle produce cold air so i asked is the ac compressor on is it on or not
