Audi Blower Motor / Fan with OEM part number 4H1820021C, a used genuine unit from a donor vehicle. This front HVAC fan assembly also replaces 4H1820021B, 4H1820021A, and 4H1820021. When the blower motor fails, you may experience weak or no airflow from the vents, or a noisy, squealing operation. It fits multiple Audi models including the A6, A7, and S8, and is compatible with engines such as the 3.0L supercharged V6 and the 4.0L turbocharged V8.
