Temperature Blend Door Actuator

The temperature blend door is a stepper motor style actuator. The HVAC control module monitors the position of the temperature blend door by counting the motor steps as it rotates. The HVAC control module drives the temperature blend door actuator motor in the direction necessary to move the temperature blend door to the position set by the temperature selection knob.
