***Air Ride Suspension - What do I do?***

[H2Much]

So, I took my ride to the GM dealer, and found a mechanic who had been with GM for over 20 years. I found out alot of things I wish I would have known before, so now I will share the wealth.

1. First of all, if you ever change the height on your H2, the dealership can actually hook it up to a computer, and get your Hummers computer to reset the height readings to your new height. Meaning, the ride height sensors won't be giving you crap all the time. This is good, because it can set its own parameters of height functionality, depending on where it is sitting after the lift. The only thing, is that this has to be done right after the lift or height change, otherwise you end up burning out sensors and compressors. I found this out the hard way.

2. Second, and I read this from someone who replied to me earlier, but the GM dealer validated it for me. You can go in and have an upload done to your current compressor, to extend it's longevity. It is an electronic upload to the computer system that controls the compressor, that will keep it from cycling as often, saving you wear and tear on your compressor. I would go and do it if you havent yet, it will save you $1600.00 on a new compressor, and almost $400.00 on a new compressor module, which they usually replace at the same time if your compressor goes out.

3. If you ever do have air ride issues, you can go in and have them connect you to their computer. They can power up and turn off the compressor manually from the computer, to determine if your compressor is bad or not. There are valves that control the air going in and out of the airbags, that could also be the problem, so you will want to make sure it's not your compressor before you get into spending too much. You will most likely know when your compressor is bad, because it won't turn on. Easiest way to tell- go to the back, and turn on the air compressor switch in the back, inside of the vehicle. If the compressor doesn't turn on on its own, you have problems.

4. Air ride problems are a royal pain in the ass, and get you aggravated more than anything, quicker than anything. If you start having little issues, take it to an absolute pro, someone who has worked on them before. Anyone else, who is not a pro with the Hummers, will just F*** everything up, and you will end up getting into it well into the thousands of dollars. It is just worth it to take it to a Dealer, or a pro, and spend some extra $$$ up front; to save the mistakes and problems and spending much more $$$ than you would of in the first place trying to fix the mistakes the first guys made. I wish I could have learned this lesson the easy way.
