So I've been reading posts about the DIC. And this got me to wondering, what the heck people were talking about. So I start looking around at stuff and realize why I haven't heard of this before. I DONT HAVE IT. I bought a fully loaded '02 Z71, so my first reaction was what do you mean I dont have it. As I come to find thru some reading the 02 Av's dont get that as an option. So I called up the dealership and they are checking to see about it for my truck, but he says it would probably be cost prohibitive. So I just gotta know. What exactly does this DIC entail and why would it be cost prohibitive?
