I have a 2005 H2 hummer that the air suspension runs when I start the vehicle and close the door. The button is off. I also noticed that it runs sometimes when I stop. Is this normal?

I don,t have the air ride on my H2, but it does sound like you have a leak somewhere. I think the compressor will come on to maintain a constant ride height with weight in the rear. If the weight in the rear is not changing but the compressor keeps coming on I would start looking for a leak.Possibly the air line?

I am having the same issue my '03! i hear a clicking around the front of the dash, and the pump turns on when it does it. i thought it maybe just maintaining height. did you get anyother answers on this?

Thanks

The air suspension pump comes on to help level the truck at a stop or low speeds. It will shut off when you get above 20 mph ( I think it is 20 mph ) That is normal for the air suspension. I never used the dash button but I believe it is to engage the system when you get hung up on an obstacle and need the extra height to get off high center.

Awesome man, i thought there was something wrong!

one other thing, when you do engage the Air lift to raise the back it does go back down on it's own after some time doesn't it? it's not supposed to stay up is it?

HAve you done any of the cold air intake, exhaust work, or superchip to yours? if so, did you have any success?

thanks again,

barry
