On more recent models of cars and trucks, nevertheless, the process works in a different way as the blend door actuators will change the circulation of air away from, or partially away from the core to decrease the amount of heat let into the interior, according to RepairPal.com, whereas older vehicles will just count on a single part referred to as a heater control valve, a part which has the ability to stop the circulation of engine coolant from going into the heater core.
