Sounds like the seals may have failed in the air shocks themselves. I also think you may have a bleeder valve problem. Follow the lines back and check the bleeder valve to see if it is leaking when you have someone else turn the vehicle on.

If the compressor is working and actually pumping out air, might need to check your lines dont have a leak by disconnecting them from the bags. If pressured air is making it to the end of the line, then bags may need to be inspected and one or both replaced. However it is more likely that the lines are leaking or the compressor pump needs a service. Just a new set of rings in the unit. Good luck, hope it helps.

SOURCE: air suspension compressor doesn't run

Hi, this is a common issue with most air ride trucks of this nature. the air compressor unit has failed and it will need to be rebuilt or replaced. its cheaper to just replace the compressor rather than to get it rebuilt. The most likely issue will be that the seal has been blown and it is unable to compress the air flow through the air lines.

Pleas rate and god bless:)

I just experience problem with a leak in one of the bags in the back n because i didn’t have the money then to take care of the problem my air compressor burned. I just recently changed the bag and I found it at this website for $160 and the compressor is $210 + shipping. They r a manufactor so what they do they sell u refurnish parts that r as good as new and cheap. U purchase the item and sent them the broken item back n they give u a credit of $50. I made both purchase an air bag n the compressor n so far everything is working fine. The air bag is super easy to change but the air compressor its a little more complicated. The website is http://www.suncoreindustries.com/ and they even sent u the instructions on how to do it urself. Hope this was helpful!

SOURCE: rear air suspension is not at level left is higher than the right

I have the exact same problem but my Left side is "Lower" than the right side.... Go Figure, Let's switch Solenoid's... Lol. I haven't seen a fix for this yet... there is 1 ride height sensor bolted to the rear but it's for both sides. the following site seems to be recommended by most Expo owners on all of the ford forums.. Check them out.
