Working Principle: The blower motor resistor is an important component in an automotive heating,ventilation and air conditioning systerm ( HVAC systerm ) . The ac blower motor resistor is responsible for controlling the blower motor speed. When you adjust the speed of the fan in the car, you are actually adjusting the current that the a/c blower motor resistor allows to reach the fan motor. The higher the fan speed setting, the greater the electrical flow allowed through, and the faster the fan motor speed
