Description
This Mercedes-Benz blower resistor is an original HVAC electrical component for the Mercedes S-Class W220, identified by OEM number 220 820 92 10. It is designed to work with the cabin blower system and helps restore proper interior airflow control in the vehicle.
Its job is to regulate the power sent to the heater and air conditioning blower motor, allowing the fan to run at the selected speed. When operating correctly, it supports smooth blower response, stable cabin ventilation, and consistent climate control performance in everyday driving.
Common signs of a faulty unit include a blower fan that works only on certain speeds, cuts in and out, runs continuously, or stops working completely. Weak airflow with an otherwise functional climate control panel can also point to a failed blower resistor in the HVAC circuit.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 220 820 92 10 before ordering. Professional installation is recommended, and coding, programming or adaptation may be required where appropriate for the vehicle system.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
