Hi to all. Our Clubman seems to have been possessed by a climate poltergeist. The air flow randomly moves from one position to the next at will. It seems that the culprit is the central drive unit. The OEM part number should be 64119270388. I've found some used ones on Ebay that *look* similar, but don't seem to have a comparable part number. Is there an interchange number that I should be looking for? Should the part itself have "64119270388" stamped on it somewhere?

Thanks in advance.
