I have no tail lights or dash and interior illumination.I have checked all fuses

Yes checked every fuse with the lights on, still nothing...only headlights

(*TESTED* fuses, not checked)! ..... TEST headlight switch... That's what powers up the tail and dash lights. http://repairpal.com/repair-shops

It turns out that someone I trusted had used a new kind of fuse that lights up red when it burns out. Thus he had thought it was red as it meant it was working correctly....he was so oooo wrong. The fuse"34" as stated earlier was the fuse, it had been replaced earlier also. But until we fixed a exposed wire in the trunk it seemed to be blown without my knowledge & thinking that the red meant good and working. Once changed& no red all is back to normal .Thanks.. Everyone for all your help. You guys saved alot of time and$.
