I have been searching for a few hours for a lumbar seat position knob. This is the large knob that lives where the seat back meets the back of the seat cushion. It is not the smaller knob that adjusts the lumbar control at mid seat height. Mine is camel coloured, which is what I would prefer but I am also in the market for a black one if needs be. It is the driver's side I need of course but I have read that this knob is used on later model Volvos and I suspect the passenger's side knob is close if not identical.
