Rear air problem

[MarineHawk]

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...

But the pump does not run when the truck is off. So what's the point of pulling out the fuse?

If the compressor is running with the ignition off the most likely cause is the air suspension relay sticking. Seen many that would intermittantly stick on. Leave the fuse out till you get A new relay otherwise you will burn the compressor out if it runs continuously.

That's the point---it IS running with the ignition off. I was worried about running down the battery and possibly burning up that damned expensive compressor.

Thanks Humtech---I hate to ask this but where is the relay and how do I check or is it just easier to go ahead and replace it and see if that works? Where might I find on of those animals?
