Replaced Airbags with Coils - Service Air Suspension Light stays on???

[love dodge]

I did all that stuff and the "service air ride" didnt go way...I just found out that my compressor and all the hoses are there...And of course all the fuses,relays,sensors and everything else still on my h2.The only thing the dealer guys did was replaced the airbags with the oem springs and cut the ground cable from the compressor and thats was it....
Thats the way this people "upgraded to coils" and charged 1600.00 the previous owner for it...
Anyways i just sent my cluster for repair on an ebay auction to replace the motors and when it came back..BANG...No more "service air ride" on the cluster..I dont have an idea why is not there anymore but i'm very happy the way it is now...
Maybe u hummer tech's know something about it and i hope it helps.Maybe if people with the same problem try to disconnect their cluster and plug back on?...
