  • AIR FLOOR WON”T RETRACT (Release air}

    Posted by Charles on June 2, 2014 at 12:40 pm

    Hi Group,

    I have a 97 Liberty Lady XL 40 and I have an air floor that covers the entry steps in front of the passender seat when running. Floor extends fine, but when I flip the switch to retract it , it stays out. Eventually you can maually push it back . The longer you wait the easier it is to push. I assume I have a bad solenoid or air release valve …although the valve seems to work fine to pressurize, but where is it?

    Could very well be an air problem, but I cured the same problem on mine by cleaning and lubricating the tracks the floor runs in.

    I assume this is with good air pressure…could be adjustment of the release side of valve for air….bad valve or bad solenoid I would verify solenoid is activating then attempt to adjust the valve. Once again feel free to call if you don’t know how or location.

    Chuck,

    I had the same problem on my Liberty.

    The solenoid valve is located on the ceiling of the steer compartment under the drivers seat.

    To test for the bad solenoid I simply transferred the wiring from one side of the valve to the other. When the slide went in but wouldn’t go out I decided that the valve was OK and then tried one side and then the other independently. This isolated the faulty solenoid which was an easy replacement.

    Thanks Chuck.

    I am mot sure these solenoids are as easily accessed in the mirage XL as the H3. It was pretty intimidating when I looked in last night.I’ll let you know when I get up the gumption to tackle the task….chuck shorley

    Chuckles,

    It does look a little scary the way stuff is packed in there, especially the valves on the bulkhead toward the steer axle but I think that is Prevost stuff and the valves you want are under or near the headlight. Trying to picture it in my mind because I don’t have a bus to look at. Jeff Rowe? Help!

    Since it was last working have you or anyone done any work in the area under the slide. I was working on mine awhile back and it would not go in fast enough so I helped it with a push and bend the rod. I replaced the piston and when I had it all back together it would only work real slow. I played with the valve adjustments and no help. I took the slide out and found that I had kinked the air line going to the piston. fixed the kink and all is good. If you can take out the slide and look at the lines and piston you may find your problem.
