Audi Blower Motor Resistor 8T0820521F – a used OEM part from a donor vehicle. This resistor module controls the HVAC blower fan speed. It replaces 8T0820521A, 8T0820521, and 8T0820521E. When the resistor fails, the blower often runs on only one speed (typically high) or stops working entirely. Fits various Audi and Porsche models from multiple years.
