Ok guys I found it (white plastic tube with black insert) . It was behind this metal bracket that held those two boxes i mentioned earlier. I took it out and took it apart and cleaned out the air hole some lint in there but pretty clean otherwise. Anyhow I put it all back together and no change. When I press the buttons for any of the lumbar/seat air pilows
the little motor just buzzes for a second and nothing. I am guessing what should happen is the motor should run until I am satisfied with the way it feels, right?
