6904249 BMW E38 E39 Passenger Door Control Module PM-BT – OEM Used & Tested

Descriere

This BMW passenger door control 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 6904249, marked PM-BT. It is designed to control the passenger side window, the mirror adjustment motors and the central locking actuator, and to report the door status to the vehicle body electronics.

Its job is to accept the commands from the switches and the central locking, to drive the window motor, the mirror motors and the lock actuator of the passenger door in a safe, controlled way and to inform the rest of the car about the door state. A properly working passenger door module supports smooth window travel, accurate mirror control and secure locking and unlocking.

Common signs of a faulty unit include a passenger window that is dead, slow or stuck, a mirror that stays still or moves only in one direction, a door that no longer locks or unlocks with the central locking, switches that stop responding, or faults that come and go with vibration or moisture. When the module fails, the passenger door may lose several comfort functions, and fault codes may be stored in memory.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 6904249 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, mirror and lock operation should be performed after fitting where applicable.
