- ADVANTAGE – The Heater Blower Motor Control Switch is an electrical component that is a part of the vehicle’s heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed. When fan speed is changed via the knob on the instrument cluster, the Heater Blower Motor Control Switch changes setting, which changes the speed of the blower motor.
- DETERMINE THE SPEED OF THE BLOWER – The change in resistance then limits The current through the motor, which dictates the speed at which the blower fan works. Heater Blower Motor Control Switch, being a mechanical component, are prone to wear and are the most common point of failure in a car’s heating system. Resistors, their construction and troubleshooting.
- SIMPLE OPERATION – On most vehicles, the highest blower motor speed setting bypasses the Heater Blower Motor Control Switch to give the fan full vehicle voltage (typically between 12 and 14.4 volts). If the blower motor still works on high, but will not work on any other speed, it usually points to a bad blower motor resistor..
