So I'm having trouble with my instrument panel lighting. I just got a new dimmer switch that I know works. I installed the dimmer switch and still nothing. I heard that it could be the acc fuse. Going back I checked all the fuses and they are all good. There was no fuse in the Acc slot in the fuse box. I tried putting a number 5 fuse in the acc slot and it blew right away. I put a number 10 fuse in the acc slot and it blew right away as well. I'm guessing it could be a short some where but have no idea where it could be. Any suggestions? All my exterior lights work such as my head lights turn signals and running lights. Is there anything i'm missing or does anyone know the fix?
