Used BMW seat lumbar support wiring harness, OEM part number 9339338. This genuine used OEM harness, also known as the seat lumbar support wiring harness, was removed from a donor vehicle. It is the front wiring harness for the lumbar adjustment system in the seat. A common failure symptom for this harness is a non-functioning or intermittent lumbar support, where the seat's backrest cushion fails to adjust or inflate properly.
