My friend has a 03 Denali and since yesterday the DIC says "service ride control". It comes on whenever he starts it. The weather has been crazy up here and it was in the 50's for a few days and then it got cold again and I think that something got wet and then froze up. I don't know anything about the ride control on these vehicle's and he would like to try and figure out before taking it to a dealer. Can someone give me any advice on what to check out to figure out what it might be?

Any help is greatly appreciated!
