I put in an after-market head unit and later that night I noticed that the dash lights didn't work. EVERYTHING else is working. (When I say dash lights, I mean the back light. Cruise light works and even when I had low tire pressure the light came on) I pulled all the fuses 3 times. I recently put in another new head unit. (Double din pioneer) and STILL isn't working. I don't think it's the light bulbs because all of them wouldn't go out at the same time. Help please!
