Description
BMW OEM HVAC flap actuator for air distribution, OEM number 8391377, compatible with BMW E38 and E39 models. Tested and verified for correct function before listing. This genuine used unit is supplied for direct replacement.
The actuator positions the distribution flap inside the HVAC housing to route conditioned air to the selected delivery point — the face-level panel vents, the footwell ports, or the windscreen defroster channel — under the direction of the climate module.
Failure of this actuator on E38 or E39 models typically manifests as fixed airflow direction, mechanical clicking or humming from the heater assembly, and climate control system fault codes being stored.
Good used condition. Verify OEM number 8391377 and model compatibility before ordering. Professional fitting is recommended, and coding may be required after installation. 14-day return policy applies.
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.
