Air Door Actuator / Motor: Description and Operation
BLEND/PASSENGER ACTUATOR
The door actuators are 12-volt electric servo motors which move the doors in two directions. The HVAC Control Module can reverse polarity to
change the direction of the motors.
The Blend/Passenger Actuator can move the temperature door in two directions. When the voltage at Pin 12 of the control module is high, about
11.5 volts, and the voltage at Pin 17 is low, about 1.5 volts, the door will move towards the Heat position. When Pin 17 is High and Pin 12 is Low
the door will move towards the Cold position. When both Pins are high or both Pins are low, the actuator will not move. The Blend/Passenger
feedback signal is a voltage signal that is supplied by the actuator to the control. The signal will be about 4.0 volts in the Heat position and 1.0
volt in the Cold position. As the position of the Blend/Passenger actuator changes, so will the feedback signal. The feedback signal is necessary
for the correct positioning of the temperature door.
DRIVER ACTUATOR
The door actuators are 12-volt electric servo motors which move the doors in two directions. The HVAC Control Module can reverse polarity to
change the direction of the motors.
The Driver Actuator can move the temperature door in two directions. When the voltage at Pin 15 of the control module is high, about 11.5 volts,
and the voltage at Pin 13 is low, about 1.5 volts the door will move towards the Cold position. When Pin 13 is High and Pin 15 is Low the door
will move towards the Heat position. When both Pins are high or when both Pins are low, the actuator will not move. The Driver feedback signal
is a voltage signal that is supplied by the actuator to the control. The signal will be about 4.0 volts in the Heat position and 1.0 volt in the Cold
position. As the position of the Driver Actuator changes, so will the feedback signal. The feedback signal is necessary for the correct positioning
of the temperature door.
MODE ACTUATOR
The door actuators are 12-volt electric servo motors which move the doors in two directions. The HVAC Control Module can reverse polarity to
change the direction of the motors.
The Mode actuator can move the mode door in two directions. When the voltage at Pin 18 of the control module is high, about 11.5 volts, and the
voltage at Pin 12 is low, about 1.5 volts the door will move towards the Panel position. When Pin 12 is High and Pin 18 is Low the door will move
towards the Defrost position. When both Pin are high or when both Pins are low, the actuator will not move.
The Mode door feedback signal is a voltage signal that is supplied by the actuator to the control. The signal will be about 4.5 volts in the Panel
position and 0.5 volts in the Defrost position. As the position of the Mode actuator changes, so will the feedback signal. The feedback signal is
necessary for the correct positioning of the mode door.
