Rear air problem

[AUHUMMER]

OK, looking to the voice(s) of experience, and trial and error, again for help. Came out to the truck ('03 H2) this afternoon after a 5 minute stop and heard the rear air compressor running---checked it out a couple minutes but it never stopped. Drove on to work and it was still running after I turned off the ignition. Ran continuously for about 8-10 minutes while I crawled under and around looking for something wrong. I was headed into a meeting and knew it would run down battery so I pulled the VSES/ECAS fuse under the hood. Anyway, I searched the threads and, of course, found related threads. Until I can use the spray bottle test to look for leaks, IS IT OK TO JUST LEAVE THE VSES/ECAS FUSE OUT? Usually my repairs require multiple fixes---the original problem and then all the crap I tear up---so this may take a few days. If it is a bag, I'll have to order---no dealer within 100 miles. As always, thanks...

Oh, I thought this thread was about flatulence.

It's likely a bag and they can be tricky, sometimes leaking badly and other times holding air for days. That threw me off when ours developed air suspension problems, I reasoned there was no way a leak in the bags could be intermittant- but that's exactly what it was.

Don't tear everything apart, just pull the bags and replace them. If it's an 03, there is a programming update you should inquire about for the air suspension.

While you're getting that update, tell them to also update everything else. Early 03's had an issue with the "auto volume" not sending a signal to the amp unless you cycle the button with the engine running.

Thanks, and as always I appreciate the help. Doesn't look like the bags are that big a deal to replace. I'll get this thing to the dealer eventually to check on those updates.

anyone have a sorce for aftermarket replacement air bags ? the dealer is probably going to want big bucks . the sorce I get my Ford/Lincoln bags from will sell replacement bags for expiditions for $180.00 a pair landed,but he doesn't have a replacement bag for Hummers .

Anybody know if its OK to leave the VSES/ECAS fuse out( stop compressor running) until I can get this sorted out? Just trying to avoid compounding problems...
