Electric fan system for vehicle

An electric fan system has a first electric blower (10), which utilizes a brushless motor (12), and a second electric blower (20), which utilizes a brushed motor (22), for distributing the cooling air to the radiator (100) and the condenser (110). The system has an electronic engine control unit which activates only the first electric blower (10) when it determines that the cooling water temperature is less than T2, and activates both the first and second electric blowers (10 and 20) when it determines that the cooling water temperature is T2 or higher. The water temperature is based on a detection output from a cooling water temperature sensor. Thus, since the electric blower (20) is not activated unless the cooling water temperature becomes T2 or higher, use of the brushed motor (22) is limited and its life is increased.
