Just to jump in here I a month ago had "service air suspension" come up on display. I went in and they told me they saw the code and would replace compressor. I have an 03 as well.

The part was also on backorder and took about 5 days to come in. They replaced under warranty (I bought certified 2003 H2).

I guess once I get the air bags in I'll have to go to the dealership to see if it's throwing any codes. Last time I was there (when they couldn't find the leak I found myself), it was not throwing any codes. I'm afraid I will go with the coil springs before I would buy a new compressor.

I forgot if you had been told to and had checked the fitting at the inside of the rig. If I have my air hose hooked up inside, it will let the air out of the airbags and the ride height will come down. Maybe the valve core is leaking or something? Try replacing the valve core (they are super cheap at any auto parts store) and maybe even get a new valve cap that is made of steel and has an o-ring inside it and tighen it down well. I know that you found one of the bags to be bad but maybe this could be something contributing to the leak?
I don't know, good luck though.
Also, as far as replacing the compressor, I know the factory one is REDICULOUSLY expensive and I plan to replace mine (if I ever have to) with a quality aftermarket VIAIR or something. They are a LOT cheaper and will be just as or more depndable.

tantric. I also wondered if it was just a connection or fitting that was leaking and not your actual air bag where you saw the leak. BUt it you are emptying the air out of the bags in 30seconds as said i would think you have a pretty good leak. Not to mention that you are probably overheating the pump and setting off a relay to keep that bags up while running.
The air pump is finally crapped out on my H2 and i will post what i use for a new one when i get around to putting one in. good luck . doug

I have not had the opportunity to check the fitting yet.. Where ever the leak is coming from, its only growing. I'm just afraid the compressor is shot now.

I can't own anything that works properly. Much like my vettes - its always somethin.

Anyone know where I can get that part that I listed in my first post?
