Hummer Forums by Elcova - New H2 owner in need of advice

Just signed up to this site and man i cant tell you guys how much youve already helped me out by just reading your post. I got a problem with my H2 the service air suspenssion came on and my ride is very low. I pressed the height control button but it doesnt do anything, it just stays lit. I can feel every little bump i roll over and when on the freeway my hummer tends to shake left to right like people are shaking it. Its kinda scary when im driving with the family. Just wanted to see if this has happened to any of you guys and may have some advice before i take it to the dealer.
