Descriere
This is a genuine Audi blower resistor for Audi A6 C6, with primary OEM number 4F0 820 521 A and alternate reference 4F0 910 521. It is an original HVAC electrical component used to control blower motor operation within the cabin heating and air conditioning system.
Its job is to regulate the interior fan speed by managing the electrical current sent to the blower motor. When working correctly, it helps the climate system deliver smooth and consistent airflow through the vents, supporting both heating and air conditioning performance in everyday driving.
Common signs of a faulty unit include the cabin fan working only on certain speeds, no blower operation, intermittent airflow, or a fan that behaves unpredictably. In some cases, weak or inconsistent ventilation can point to a failing resistor affecting normal blower control.
This is a used original part, removed from a vehicle and tested before sale. Please match 4F0 820 521 A and 4F0 910 521 with your existing unit before ordering. Professional installation is recommended, and wiring or connector condition should also be checked during fitting.
