1999 Chevy Cavalier Interior has now power

So I was just driving down the road when I lost power to my stero, thinking that it was probably something that fell out of the stero I took it out to inspect all of the wires, but to my surprise everything was still intact, I then thought well maybe I blew a fuse of somesort, because I lost all interior power, my interior lights dont even go on and I dont get that nice little ring when I leave my headlights on or leave the key in the ignition, so I then checked ever fuse that I had, yes time consuming but, they were all fine. So now im lost im not sure where to check. Does anyone have any ideas it would be greatly appericated as this is going to reall make my long drives back home (OVER 600km) a long one without any kind of stero or radio, thank in advance.
