Real men fix their air leaks.
OK, just breaking your chops. I did the same thing for the last coach. My current XLII has Prevost installed solenoid valves that do the same thing so apparently they figured it out.

I think it’s the little plastic auto valve where both air lines go into it where the two little pins rotate on the plastic to add air or release it , I think it could be replaced but it would do the same thing in no time flat, you can not hear any air leaking or hardly see bubbles with soap spray so this is the best fix ..thanks for breaking my chops it makes me laugh!!!!

I can do that because I had the same leak. It was in the air switches that control the lumbar support. As it turns out fixing it only was a temporary thing and I ended up plugging the air lines to that switch.
Same thing on the current coach, but it has the solenoids in place and the seat is on the Prevost side of the aux air system.

cool fix.could you post a part number from grainier thanks jim

Solenoid valve 2 way part number 5WND0

thanks a lot I will add one to my seat

I had to plug the same leak to the lumbar supports on my drivers seat. Is there a fix for this connection or have we all just plugged this leaker?

Change seats mine does not have air lumbar it is electric lumbar with little air pump

I can only speak about the lumbar air switch on my Liberty. It was leaking so the obvious fix was to replace it. The second switch did not leak initially, but the lumbar supports would deflate after a while so I had to continually keep pressing the switch to re-inflate the support. After a while the switch was back to leaking so I just gave up and capped the lines.
An electric lumbar support is the answer. I have that on several of my cars and it is always in the right position and I never have to re-adjust it.

I just called Grainger, they said that switch has been discontinued, but have a few left, reduced to $29.71. I just ordered one.
Is there a main air line going to the seat, that this switch could be put into, to isolate all leaks in the seat when the key is off?
-
Find air line in steering bay going to seat I put ball valve then solenoid. Just incase solenoid screwed up I could still shut it off when parked …

Good Idea Peter…..thanks

Just to repeat what I have previously posted, I have ball valves on all my house air circuits,
Liberty takes air from the converter connection provided by Prevost and feeds a manifold. From the manifold air lines go to the various air operated systems and devices in the house, ranging from the pocket doors to the generator air bags to the dump valves, bed lift, and floor slide.
If I am losing air and want to know where to start looking all I have to do is turn off all the ball valves wait a few minutes, and open the valves. The circuit that is leaking will be evident because you will hear rushing into that circuit as soon as the valve is re-opened.
Some time I will do the same for the Prevost circuits which come off of two manifold blocks on my coach. The problem is those blocks are very small and the use of push in fittings is required which I was forced to use on the converter side of things. I will have to create new manifolds which will allow the use of compression fittings and provide room for the ball valves. It will be a serious project and likely will not happen until I take on the job of replacing all the fittings on the coach.
