    Air ride compressor

    Hi there,

    I had just replaced the air ride compressor with a used one, but not it takes kind of long for the car to rise to the right level. Do you think it might be something i did wrong or there is a air leak that caused the other compressor to brake and the problem is still there?
    What should I check first? When there is 3 people on the back seat the compressor works for several minutes. Is that normal? Maybe I just pay too much attention to it now.....
    Thanks!

    If the compressor assembly levels the car and shuts off, that's OK. If it cycles on and off, even every 5 minutes, you have a slow leak.

    Actually, it should take no more than 15 - 20 seconds to adjust level.

    Thank you!
    Well it brings the car at the right level, but I think it takes too long.
    Do you know if there is a certain pressure that the compressor should pump out air and how/if I can check that?

    The replacement pump could be worn and weak.

    Also, the pump usually wears out as a result of a leak that caused the original compressor to overwork.

    Two possibilities.

    Thank you guys!
    I'll try to see if there is a leak in the system.
    OOoo, another question: Is it possible that the shocks are loosing air or just the air lines?

    Use the tried and true technique of getting the car up on a lift, start the engine and level the car. Shut down and spray a soap solution over the shocks and lines. Bubbles ??? Leak. You may have to trace the problem all the way back to the compressor connector.
