Description
This Mercedes radiator fan control module is a genuine OEM electronic cooling unit for the ESG 300 application, matching Mercedes 300 models as marked on the part. The primary OEM number is A0255453232, with alternate reference 898940000. It is an original control unit designed to manage the electric radiator or auxiliary cooling fan circuit.
Its job is to regulate fan operation so the cooling system responds correctly to engine temperature and air conditioning demand. By switching and controlling fan speed or activation at the right moments, this module helps maintain stable operating temperature, supports condenser cooling, and protects the engine from excessive heat in traffic or warm conditions.
Common signs of a faulty unit include a radiator fan that does not run, runs continuously, cuts in at the wrong time, or causes overheating in slow driving. In some cases, air conditioning performance can suffer at idle, or fault codes may appear relating to the cooling fan control circuit.
This is a used original part, removed from a vehicle and tested before sale. Please match A0255453232 and 898940000 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle configuration and diagnostic procedures.
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.
