Description
This rear right door control module is a genuine Mercedes unit for the W203 C-Class, supplied under OEM number A2038200826. It is the electronic control unit fitted to the right rear door, designed to integrate the door’s electrical functions with the vehicle’s comfort and body systems.
Its job is to manage and coordinate commands for key door-related functions such as power window operation, central locking communication and other rear door electrical features. By processing switch inputs and exchanging signals with the wider vehicle network, it helps the rear door respond correctly and consistently during everyday use.
Common signs of a faulty unit include an inoperative rear window, locking problems on the affected door, intermittent switch response, loss of communication with the door electronics or irregular operation of related comfort functions. Electrical faults in this module can also cause the rear door equipment to stop working altogether or behave unpredictably.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number A2038200826 before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle equipment and system configuration.
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.
