PURPOSE: To blow out cool air into a car room and accelerate the cooling in the car room by driving a blower fan motor when the outside air temperature is higher than a predetermined temperature even if the engine water temperature is lower than a reference temperature.
CONSTITUTION: When an ignition key is turned ON, an air conditioner is made operational; if the outside air temperature TA detected by an outside air temperature sensor 4 is higher than a predetermined temperature T1, a blower fan motor 8 is driven; if the engine water temperature TW is lower than a reference temperature T2, the fan motor 8 is kept stopped until the water temperature TW reaches T2. Accordingly, the fan motor 8 can be driven even if the engine water temperature is lower than the reference temperature, thus cool air can be quickly blown into a car room when the outside air temperature is comparatively high and the car room temperature is high in summer, for example.
