BLOWER MOTORS

The blower motor enables you to control the fan settings of your air conditioning (A/C) system. It operates the blower fan, pushing air through the heating, ventilation, and air conditioning (HVAC) system and out through the vehicle's vents. Blower motors are designed to operate at low, medium, medium-high, and high speeds. Indications of a malfunctioning blower motor include unusual sounds and diminished or absent airflow. Overall wear, and an open circuit in the power-side circuit can lead to blower motor failure.
