Question about 2005 Hummer H2
Im getting a message in the message display to service the air suspension.. is this expensive to service or is better to replace it.
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!!!

U will need to have the system self tested by the dealer, they should quickly find the problem since they have the test gear to diag the issue, then replace the part that is defective yourself.

I have a 2006 H2 SUT Orange Special Edition. I 126,000 and have never had the truck in for service with the exception replacing the rear air springs (bags) about a year ago which is normal for the airbags to dryout and crack after 6 years in Florida.
About a month ago my air pump/compressor assembly starting making a loud clicking noise when the system activated by the leveling sensors. A week ago I notice that the airbags were no longer inflating, and were slowly deflating. It took 3 days for the airbags to deflate to the point where the ride was seriously affected and the rear end sagged noticably.
After doing alot of research and discovering the cost to replace the compressor assembly with includes the dual pumps, air dryers, compressor tank, and other valves and hoses is $1500 for the part plus labor which I would estimate at $200-300. I have read about several spring coil alternatives with a total cost of $150-$1200 for the springs and $200-$300 for labor. Neither option sounded that great to me.
The Solution: I woke up in the middle of the night and I thought "I wonder if I can backflow air into the compressor tank using the auxillary air compressor outlet located in the trunk. I tricked the truck into activating the pumps which opened the valves to the air compressor tank. I needed to be sure the driver door was shut and repeatedly turn the truck on and off, the first 15 seconds after starting the truck would activate the pumps and compressor to try and fill the airbags. The airbags would not fill because the airtank was emptly due to the failed pumps, which were making noise but not filling the airtank which supplies the airbags. I then connected the auxillary air outlet to a high pressure air hose at my local gas station. While the truck was activating the pump and compressor for the 15 seconds following startup, the valve was open to the airtank and I was able to backflow air through the auxillary air outlet in the trunk and fill the airtank in the compressor assembly. Once the airtank was full at about 100lbs, the truck was able to use the airtank to then fill the airbags. I have no idea if this is safe or how long this will last but I suspect the air will remain in the airbags for a week or so and it only takes me a few minutes to fill the airtank, so I'll keep you all posted on how this workaround will last. I dont mind 2-3 minutes a week to save $1800!
