Air Ride Suspension

[jbrown]

I recently bought a 2003 H2, 2 days ago my air compressor wouldn't shut off an it had both bags filled to damn near explosion. I released the air out the lines an it was fine, So today i went out an the backend was lowered all the way an the compressor wouldn't come on at all. An the incab ride height adjustment was blinking an blinking so i disconnected the battery thinking this would some how help. It didn't no the compressor don't kick on an the ride height button does not work at all an the service air suspension light stays on in my dash. I'm 60miles away from a dealer an out of town on business. So any ideas on what if anything i could check or do to possibly get the thing to work? Is it a ride height sensor that went hey-wire or is it something more serious that i'm dealing with. I've connected a T with a air valve on to manually inflat bags for now. So its atleast driveable but i'm hoping i can fix this myself. Thanks for any help or ideas.

I just recently had the exact same problem. There is a wiring harness that connects the compressor to the body of the truck. It is a wide amp style connector. Check the wires on both sides of that. One of my wires on the truck side of the harness was completely broken on my truck. It was actually the red wire I believe the top wire towards the front of the truck. Stealership wanted $450 to replace harness. I just pulled the pin out with a connector tool soldered it together and reassembled shes been sitting right since then. Good luck.

Those years were prone to the compressor relay sticking and failing due to the heat from being mounted close to the left exhaust manifold. I would check that first
