Abstract
A device for controlling an opening angle of an air mixing damper used in an automotive air conditioning system is disclosed. The device has an actuator for operating the air mixing damper and a blower for blowing the air. The device comprises an ambient air temperature sensor which is disposed on a front grill of an automobile for detecting the ambient air temperature at the exterior of the automobile and for providing a control signal, and a measuring circuit which computes the ambient air temperature data necessary for controlling the actuator and blower based on the detected ambient air temperature. The device controls the opening angle of the air mixing damper in accordance with the measured results.
