| You have a picture posted. In that picture, the switch is in the Dump engaged position. The switch should send air to the pilot line (smallest line) on the air bags. The pilot line causes them to dump. When you cut off the air to the pilot line, they valves go back to auto level functionality. So, if you turn that knob i mentioned to the left, and cut off the pilot (dump) line pressure to the auto level valves, then they will air up if pressure is in tank.
So, you have 3 possibilities here.
1) The switch is in the dump position as per your picture.
2) You have malfunctioning auto level valves.
3) You have insufficient air pressure in the tank.
And it is just that easy. Also note that all parts are standard semi truck Firestone air suspension components. | |
