Looking for the Air dump Solenoid. Can anyone share possible locations? A picture of what it looks like would be helpful.
The air dump solenoid valve is the two center valves on the six pack. Six pack for the front is located above the steer axle mounted to the underside of the floor.
Recommend you block the coach before going under it or put the coach on a pit
Diagram (linked below) of the 6-pack manifolds.
As Rudy says, when you "dump" the air in the suspension you are using the 2 middle solenoid valves in the 6-pack manifolds.
Why do you think you need a solenoid?
If the coach won't lower on a particular corner, check the dump ports on the manifold for mud dauber nests first.
