Re: Second air ride suspension compressor
$3800 for a new compressor? That's why they call them stealerships! I think dealers see a Hummer with the air suspension and use the shotgun approach. It's not that complicated, sensors tell the pump to inflate one of the air bags. Bad, muddy or corroded sensors or a broken or cracked air line seem to be the most common problem areas with the air suspension. If you fix it yourself I'd go to another dealer to reset your DIC warning. I found an old thread here where they said they reset the DIC by disconnecting the battery for 30 minutes, but Humtech would know best. That's one reason why so many people have gone to springs in the rear.
