AB322000P MAHLE Fan, interior

MAHLE's AB322000P Interior Blower is a critical part of the vehicle's electrical system, responsible for circulating air within the cabin. Typically used in interior components like air vents and climate control systems, this blower motor ensures efficient airflow while minimizing noise pollution. Its German origin reflects MAHLE's commitment to quality and precision. Blower motors are responsible for forced-air circulation within a vehicle’s HVAC system. Typically located within the HVAC housing, these multi-speed electric motors drive a fan to move air across the heater core and evaporator, distributing heated or cooled air through the vehicle’s vents. Construction commonly includes a squirrel-cage blower wheel, an electric motor with brushes or brushless design, and temperature-activated control resistors. Performance is rated by cubic feet per minute (CFM) and voltage requirements vary based on vehicle application. Failure modes often include motor burnout, resistor failure, or physical obstruction of the fan wheel.
