30 degrees outside so i'm useing heater, not a/c. Problem is too much heat with no way to decrease it, other than redusing blower speed or turning unit on and off

Auto climate control uses the ac regardless of the outside temp.

Blend door motor could an issue as well.

Once again, is the ac compressor coming on?
