Topic: System Aired Up, Bags Will Not Pump Up

Posted By: sealevel ram on 09/29/11 04:28pm

I'm new to my 2004 Winnebago Ultimate Freedom, and to DPs in general.
Started to leave today. The air system pumps up fine, alarm goes out, pressure is 100 PSI, but the air bags do not inflate.
Anyone else have this problem, or know anything to try or look at?
Don't hear or see any obvious air leaks. Everything else air works (brakes,etc).

Do you have an air bag dump switch on the dash that needs to be reset?

I've got a little "Rabbit" on my HWH control panel that will fill the bags. Maybe you have a button as well?

That may be the problem. I don't know where the actual valve is located.

Seems wierd to me that NONE of the air bags will inflate?.Most DP have seperate solinioids for front and rear air bag systems.Maybe the Hydralic Jack air dump switch is stuck in the dump position?

I had that problem once and it was a valve that controls the height of the airbags. On mine it was the valve right under the left front wheel. The valve got stuck open and it was blowing air through a little hose. Had the valve replaced and the air bags inflated right away. But I have a Freightliner chassis, not sure what yours has. Now you mention that you were all charged up at 100lbs of air. That is not fully charged. Mine goes up to 120lbs of air before it equalizes.

Yes, it says "Travel". Mine does not have such a button.

Thanks for all the replies. Have a lot to think about.

Don't think I have one, but define "Rabbit".

sealevel ram......My BIL has a 2004 Itasca Meridian and had the same issue when his was new. There is a valve up front that goes bad. If you connect air to the fitting at the front of the coach for tow truck use, the bags will air up. His only occasional would stick. PM me if you don't resolve the issue and I'll find out which valve went bad on his.

My 2000 37G Discovery on a Fleetwood chassis has a dump valve operated by a slide lever. On start up, I frequently have to flip the lever a couple of times before I hear a release of air and then the suspension will inflate. I have found it I wait until my air is at it's maximum (100+ #) it is easier to get it to release.

there are two valves involved.so I doubt that both valves stuck open at the same time.More likely the switch has stayed on if in fact thats the problem

Just to document for future reference, I took my machine to my local friendly RV mechanic.
He checked everything over, undid some air lines, aired up and down, leveled the coach a couple of times, and now everything works.
Must have been a stuck valve that somehow got loosened up or something. He suggested I get a spare height control valve, which is sort of the heart of the system, and either install it or keep it in reserve.

Sealevel, I have a 2002 Winnebago Ultimate Advantage. I had that problem once. Pushed the store button, jacks came up but the bags did not inflate. A friend had me put the coach in drive and move it forward about 2 feet hitting the brakes once after each foot to stop. Dont know why but on the second brake stop, the bags began inflating and havent had the problem since. Hope this can work for you.

Maybe that would have worked also in my case. Thanks for your (and everyone's) input.

I had this problem with my American Dream. Front air bags did not inflate. It was the piloted dump valves located in the wheel wells. I replaced both @ about 35 bucks each and about 1/2 hour to change out each. All is well...
