アコンフアン制御装置。 A condenser fan is attached to the radiator and condenser installed in parallel to air-cool the condenser, and a radiator fan is also attached to air-cool the radiator and condenser, and the temperature is controlled based on the engine coolant temperature, air conditioner switch, and refrigerant pressure switch on/off. In the vehicle engine and air conditioner that control the respective rotation speeds of the radiator fan and condenser fan, the power transistor controls the drive current of the radiator fan and the condenser fan, and the engine coolant temperature, air conditioner switch, and refrigerant pressure. A vehicle engine and air conditioner fan control device comprising: an electronic control circuit that controls the duty of each of the power transistors at startup to be greater than after startup based on on/off of a switch.
