      I have a 2019 Sierra 1500. Is there a sensor that is preventing my defrost from blowing full speed at any time? It seems if I adjust the temperature dial down, it will allow the defrost to blow…and if I turn it up, it will then shut it off. If there is a sensor, is there a way to override it?
