    Test it first. Do you have a foot bicycle pump?

    Get a fitting with a Schrader valve that you can attach to the compressor's output line then clip the pump on to it; I seem to remember that a healthy compressor puts out about 220 PSI. That's what mine puts out after I rebuilt it.
    Vehicle is a 2000 Vogue.

    Re: I'm about to give up on EAS

    So I pulled the compressor today.

    The O ring had melted between the cylinder and the head of the pump, the new cylinder and the piston had little to no resistance. A piece of the reed valve had broken, there is also now a slight gash in the face of the cylinder, presumably from the reed valve.

    Long story short, new compressor ordered from Island 4x4 $238 shipped to California.

    Will post back with results!

    Nice. Do yourself a favor. Use a silver sharpie marker and write the date of the install in the compressor. I did this for mine and the fuse box and steering dampener etc etc. then if I lose my notes I still have a record and the next owner as well.

    Consider the airline tubing-old, as part of the problem for an older p38. I had success with running some new tubing to the new airbags. It totally fixed my issues. The bag-tubing connections were just that much better . Assuming your air compressor/seals are good then don't forget the possibility of perished/old, oxidized tubing when you troubleshoot this problem.

    It pays to remove the air dryer canister and inspect for cracks as they are prone to crack which will cause your compressor to keep going.

    Mine is leaking through one of the solenoids, only when changing height.

    Take a vacuum hose, about 50cm, put one side in you ear, with the other end you go along all parts in your system.

    The nylon tubing doesn't age but it will have a groove in it where the O rings sat previously so can leak after it has been disconnected and reconnected. This is why RAVE says to trim a couple of mm off the end and chamfer with a pencil sharpener so the new O rings bear against a new section of the tube.

    Re: I'm about to give up on EAS

    New air pump installed and she rises once again!! However, the pump will continuously run, shut off for 5 seconds and run again.

    I believe I found the source of the air leak at the air tank, where the line plugs in. I can hear air escaping ever so slightly.

    Has anyone ever fixed or repaired the air tank aside from replacing?

    Reinhoud you are a genius! With the vacuum hose I was able to narrow down the leak to the rear passenger airbag fitting and found some very minor leaks at the valve block.

    I trimmed the airlines and all is well now!

    Spot on, this was the problem, however leaks wouldn't show up with soapy water. A small piece of tubing directly to the ear and you can hear everything.

    Re: I'm about to give up on EAS

    Ok, so I thought I had solved my problem but it does not seem that way anymore. I took the truck off-roading and noticed the air compressor was almost always on, at least 65% of the time it was running.

    Also, every morning the compressor runs for 2-3 minutes then its off, or at least I thought it was. It definitely isn't running at every stop light/stop sign as before.

    I did some testing last night, I drove the truck around an empty parking lot for 10 minutes at a time and timed how long the compressor would run.

    Wade Height
    Run 1 = 3 Seconds
    Run 2 = 1 minute 30 Seconds

    Standard Height
    Run 1 = 3 minutes 55 Seconds
    Run 2 = 3 minutes 45 Seconds

    Highway Height
    Run 1 = 1 minute 45 seconds
    No Run 2


    I can leave the truck in Wade Height for 2-3 days and it will not Self Level. If I park anywhere in Standard Height it will self level and be close to access height by the time I return.

    I've also noticed that sometimes the front end will dip while driving and then pop back up when I come to a stop.

    I've sprayed and sprayed and used the hose to the ear to look for leaks and I can find none.

    Are my brand new airbags leaking? NRV's or Bad Height sensors?
