PURPOSE:To permit the max. efficiency operation by allowing the first mounting and demounting side connector connected to the resistor of a fan motor and the second mounting and demounting side connector for directly connecting a motor and a fan switch to be selectively connected to a fixed-side connector, in a fan-motor control circuit for the air conditioner for car. CONSTITUTION:A fan motor 2 and afan switch 4 are connected thrugh a fixed- side connector 10, and the first mounting and demounting side connector 11 having a resistance connected and the second mounting and demounting side connector 21 having a relay 12 for directly connecting the fan motor 2 and the fan switch 4 can be selectively connected onto the fixed-side connector 10. When the fan is used as an air conditioner, the fan is connected to the first mounting and demounting side connector 11 side, and when the fan is used as heater, the fan is connected to the second mounting and demounting side connector 21, side, and therefore, the max. voltage can be applied onto the fan motor without generating a voltage drop, and the max. amount of wind can be obtained by the fan motor with the max. efficiency.
