6924933 BMW E38 E39 Co-Driver Door Module PM-BT – OEM Used & Tested

Açıklama

This BMW co-driver door module is a genuine OEM electronic component for BMW E38 7 Series and E39 5 Series vehicles, fitted in the passenger side door. Primary OEM number 6924933, marked PM-BT. It is designed to manage the power window, the mirror adjustment motors and the central locking actuator of that door, and to exchange status and command signals with the vehicle body electronics.

Its job is to react to the window and mirror switches and to the central locking commands, and to drive the motors and actuators in the passenger door safely and in the correct sequence. A properly working co-driver door module supports smooth glass movement, accurate mirror positioning and dependable locking, so the passenger side comfort functions behave exactly as the factory designed them.

Common signs of a faulty unit include a passenger window that is slow, stuck or completely dead, a mirror that does not move, a door that does not lock or unlock with the remote or the central locking, switches that work only sometimes, or functions that disappear and return at random. When the module fails, the door may lose several comfort functions at once, and the body electronics may store related fault codes.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 6924933 before ordering, and check that the connector type and the passenger door side match your original unit. Professional installation is recommended, and a diagnostic scan and a check of window and mirror operation should be performed after fitting where applicable.
