What is the Heater Blower Motor all about? The heater blower motor forces air through the vents. You are able to control the speed of the motor through switches, buttons, and dials on the dashboard. The motor contains a resistor which allows it to change the speed of the fan. Without this part you will not be able to change the speed of the airflow from the blower motor.
