There is a little door between the steering wheel and door. It opens up to a little compartment that you can hold something small in. You can remove that to find the fuses. On the back side of what you removed is the "map" as to what all the fuses are for.

I found that while checking my fuses that i had pulled out what looked like a black plastic "fuse puller" that was actually some kind of jumper. I had accidentally re-installed it reversed. I reversed it back to its original position and all lights, clock, radio, etc.. work normal now.

It is the fuse inside that yellow fuse holder on the lower left side that is bad. Not the one that says audio that is the problem you can not see the fuse but it is in that yellow holder.
