"2002 RD cab suspension wont raise from resting position, i know it normally wont raise until somewhere around 75-80 psi in system, but neither will the seat (seat may have air to it at lower pressure and just wont raise my by butt till its gets to this point IDK), but now the seat will raise, but not the cab even at 130psi, is there a valve, other than the leveling valve under rear of cab i should be looking at? \n"
