8376070 BMW E38 E39 Door Window Mirror Module PM-BT – OEM Used & Tested

Description

This BMW door window and mirror module is a genuine OEM electronic component for BMW E38 7 Series and E39 5 Series vehicles. Primary OEM number 8376070, marked PM-BT. It is designed to control the power window motor, the mirror adjustment motors and the lock actuator inside the door, using the signals from the door switches and the vehicle body electronics.

Its job is to turn each switch command into the correct motion of the glass, the mirror or the lock, to watch the motor load and end positions and to report the door status to the rest of the car. A properly working window and mirror module supports even glass travel, precise mirror adjustment and dependable door locking, which keeps the daily comfort functions of the car working as intended.

Common signs of a faulty unit include a window that sticks, drops or refuses to move, a mirror that does not adjust or fold, a door that stops responding to the central locking, switch functions that come and go, or a door that shows several faults at the same time. When the module fails, the comfort electronics of that door may stop working altogether, and fault codes may be stored in the body control memory.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 8376070 before ordering, and check that the connector type and the 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.
