SMALL AIR PUMP MAKING NOISE AND GOING BAD

I have a 2008 holiday rambler imperial with tag and appx 4 mos ago a small very quiet sounds like air pump just inside the drivers frame rail and just at the back edge of the drivers front tire started coming on while parked more often and also louder it was running for 5-7 seconds then 20-30 seconds and now it is extremely loud and stays on. i don't know what it pumps up or what it actually does. It sits in a tray hanging from the frame and with the tires turned the housing it sits in can be seen just behind the front left tire. i stopped the motor/pump by disconnecting the batteries. anyone know what it might be/ is it rebuildable /or just replace it and where/ appreciate any help

    the air pump fills a small tank with air so when your auto air leveling needs air it always has some no mater how long its been sitting.
    if its running a lot you either have a leak or the pressure switch is bad and it just runs and runs trying to fill a already full tank.
    if the pump is shot I don't think it is serviceable. could take it apart and see if there is any thing wrong with it.
    if you want to shut it off there is a fuse for it in the side compartment.

    sounds like the electric air compressor that keeps your air leveling system supplied with air to keep the coach level. Thats if you have an air suspension leveling system.
    Turn your air leveling off and it may stop. If it does then its confirmed.
