The heating system only works when it is mildly cold or warmer. When it is really cold (40 and below) she refuses to heat. The blower motor in all possible positions works just fine. The issue is that the air is no longer heating. Pretty vague, I know but need to know as winter is definitely here.
As a side note, there are other electrical problems such as the car alarm no longer works right, and the electronic temperature/instant mileage/tire pressure gauge in the middle only works sometimes, which also may be a temperature issue as the car is always freezing.
