WebActuators control the airflow within the HVAC system itself and help regulate the mixture of hot and cold air by sending it to the required position within the passenger cabin. Resistors have a similar function, but instead of controlling the temperature of the air, they control the power of the airflow via the cabin blower fan speed.
