When I started having problems with my air suspension, I opted to go with springs and coils in the rear to avoid all the high costs of repairs down the road later. I don't notice any difference in ride and I'll sure miss all those headaches later on.

In the back door compartment to your right is a valve with a switch for compressed air to fill tires & such. It uses the same compressor to fill your rear suspension. It bypasses the hight sensors for your rear end. If it turns on your compressor should be ok. If not, It could be a fuse or bad compressor. Start there then consider your options
Hope this helps

Air suspension hummer h2


Your vehicle is equip with air bag system. You probably experiencing an air lost due to air bags leaks or your leveling valve is exhausting air at the exhaust port. Here is what you do. Spray soap with water on spray bottle and spray around the air suspension area. when you see bubbles coming out that's the leaks. fix it. Good luck.

My Hummer H2 is leaking air from both the left


It's not likely that the bags are leaking unless you see physical damage, it's more likely that the compressor exhaust solenoid is bad. There's an updated compressor kit available from GM that requires calibration after assembly. Not cheap.

Air compressor keeps running what may cause that


it is possible that a leak has occured or that a sensor has come loose indicating to the compressor module that the air bag still needs to be inflated. proceed underneath to each bag and lines and listen. if no leaks are heard then look for arm near the axle that mayhave come loose also sensors on the bags themselves.

Is there a reset button for the compressor-air suspension


When I replaced my air suspension bag it reinflated upon starting the Hummer. I did not have to reset anything. You may check the fuses in the event it ran so much to blow one and prevent the compressor from burning up.

Your vehicle should have air bag suspension in the rear. It probably needs replacement.

Air Suspension service for a Hummer H2 2003


Replacing with new airbags for the Hummer will be expensive because it is not a permanent fix. I Would go with springs. I understand people enjoying the air ride but I promise it is more trouble than it is worth. Compressors have a 100% failure rate. What will happen is the airbag will end up getting a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag kills the compressor and you have to parts you have to constantly keep buying. With air suspension there is never a permanent fix. I would recommend going to strutmasters.com and taking a look at the conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. And for a very affordable cost. I added the link below so you can check it out. http://www.strutmasters.com/hummer-suspension-parts-s/96.htm Hopefully this will help Good Luck!!!
