all my dome lights in my 03 g35 sedan arent working.. since my cousin accidently tugged on the passenger sun visor too hard, all my light wouldnt turn on the wire connected to the visor ripped...
could that be the reason why all lights aint working? or could it be some fuse?
i checked all fuses in 3 areas no burnt ones...

 

If they all are out, it's the fuse.

 

My visor light blew out & it shorted out my dome lights! Luckily I was under warranty & the dealer just replaced the whole dome assembly & the visor. I hope that is not the case with you, the parts were expensive!
