i keep getting a reading telling me to check air suspension?the air leaks out about 5 or 6 days but when it does it goes all at once.when i push the button to inflate the ride heigth is at the max .whats up how or what needs done to get the right height and not have to keep pumping it up.

 

Since you dont have access to a GM Tech 2 I would say my best guess is that you have a bad air bag, with the vehicle parked used the increased ride height button to pump the ride height to its maximum. Then using a mixture of soapy water in a sprayer spray each air bag and carefully inspect for a pin hole leak.

I will suspect that you will find one very close to the bottom of the airbag assembly. If you do order a replacement set and install them. The installation is an easy process and does not require special tools. Start here. If it is the bags once installed coat them with silicone spray every time you change the oil and you will never have to replace them again. Don't just jump into replacing the air suspension with a spring conversion.

Having owned 3 H2's I can tell you for a fact nothing beats the ride and flexibility of the air suspension option. My 05 and 06 had it my 08 doesn't and if I could cost effectively switch from spring to air suspension I would in a minute! Hope that helps
