579 air ride seat being weird.

So I have one of those idiotic seats that goes down by itself when you are not sitting on it.

It's in a 5 year old 579.

Today it decides to slowly go up and down by itself while I'm driving and the adjustment on the left side will not make it go down like it usually does.

I have to take the skirt off the bottom at check it out but I'm assuming there is some kind of leveling valve like on the tractor or trailer that is responsible for the seat height.

I hate these kind of seats and I don't need it to lower if I'm not sitting in it. Stupid gimmick.

Does anyone have any knowledge about these seats?

Thank you
