I have a 2007 Silverado with 4000 miles on it and the Auto-Trac system. Today I tried the 4wd for the first time and nothing happens when I turn the dial. No flashing lights, no 4wd engagement, nothing at all. I called my dealer and was told they had never heard of such a thing occurring on the 2007's. Has anyone had a similar problem or know anything about it. I would appreciate any thoughts on this problem.

I also have a 2007 with 6,000 miles on it and I have noticed that the 4wd seems to be loud compared to my 2004. I have actually thought about taking it in and have them look at it. Good luck
