This used genuine OEM Audi blower motor resistor, part number 8T0820521E, also replaces 8T0820521A, 8T0820521, and 8T0820521F. It controls the fan speed in your HVAC system; when this resistor fails, you may lose certain blower speeds or have the fan only run on high. Pulled from a donor vehicle, this unit is ready for installation.
