Description
Mercedes fan control module for ESG 600 systems, supplied under primary OEM number A0255455932 and alternate number 898950000. This original Mercedes unit is used to manage the electric cooling fan circuit and is the correct style of control module for the model applications identified by these part numbers.
Its job is to regulate auxiliary or engine cooling fan operation so airflow responds correctly to engine temperature and air conditioning demand. By controlling fan speed and switching logic, the module helps maintain stable operating temperatures, supports condenser cooling, and protects the vehicle from overheating in traffic or during high thermal load.
Common signs of a faulty unit include a cooling fan that does not start, runs continuously, cuts in at the wrong time, or causes weak air conditioning performance when stationary. Overheating in slow traffic, intermittent fan behavior, and fault-related electrical issues around the fan circuit can also point to a failing control module.
This is a used original part removed from a vehicle and tested before sale. Match the exact OEM number before ordering. Professional installation is recommended, and wiring, connector condition, or adaptation procedures should be checked where required during diagnosis and fitting.
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.
