Grand Voyager V6-3.0L VIN 3 (1998)
Air Door Actuator / Motor: Description and Operation
Driver Actuator
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.
