I just got back from the local dealership this morning to have the service air suspension light and compressor checked. After reading all your threads about air bags/air compressor issues made me nervous. I was really hoping the worse scenario was just the sensors. Anyway, my service guy asked me if I did anything to the suspension and I said no and lo and behold he told me the previous owner replaced the air bags with coil springs woohoo! The best news I've heard coming from a dealer. He told me that the light will occasionally come on as I already knew thanks to our great forum and same goes with the compressor. I just wanted to let you know that without all your knowledgeable information and suggestions I will always be in this state. Thanks to all and remember, HUMMER like nothing else!!!!!
