interior illumination problem

No. Its either blown or not.

ok.  But as for the bulbs.  All of them blew at the same time? Farfetched but are they like christmas lights?  One is out so they all go too?  And that can cause the head unit to not work also?  Like I said, the fuse that runs the interior lighting (excluding the dome) also runs the lisence plate lights and they both are running fine.

I also do not have much money so I couldn't afford to take the car to a shop or anything.  I  need a simple solution.

O.K.  I have changed the bulbs.  They are all good now.  There was one that was out.  Anyway I may have something t hat may help someone to help me solve this.  There is a white wire with a green stripe (all I know is that it was on the original stereo and did something), and yesterday I accidentally connected that to the grey wire and the illumination lit up just for the air controls.  Can this help me to narrow the search field of possible problems?
