The present invention relates to a resistance device for a blower motor. The resistance device comprises one or a plurality of serially connected resistors (R1, R2, R3) forming a voltage divider capable of providing different supply voltages to a blower motor. The resistance device further includes a thermal fuse (11) formed to irreversibly separate the resistors from the blower motor when the temperature of the resistors exceeds a first threshold value. The resistance device also includes a temperature switch (12) formed to reversibly bypass one or a plurality of the resistors if the temperature of the resistors exceeds a second threshold value that is less than the first threshold value. It is possible to reduce the maintenance cost of the ventilation system of a vehicle. 본 발명은 송풍기 모터용 저항 장치에 관한 것이다. 저항 장치는 상이한 공급 전압들을 송풍기 모터에 제공할 수 있는 전압 분배기를 형성하는 하나 또는 다수의 직렬 접속된 저항들(R1, R2, R3)을 포함한다. 또한, 저항 장치는 저항들의 온도가 제 1 임계값을 초과하면 저항들을 송풍기 모터로부터 비가역적으로 분리시키도록 형성되는 온도 퓨즈(11)를 포함한다. 또한, 저항 장치는 저항들의 온도가 제 1 임계값보다 작은 제 2 임계값을 초과하면 하나 또는 다수의 저항들을 가역적으로 바이패스시키도록 형성되는 온도 스위치(12)를 포함한다.
