Ok i just bought a 03 g35 sedan and it has no dome lights map lights or the lights above the back doors. What could cause this besides a fuse?

 

Fuse most likely. Have you checked it?

 

Unhook the negative battery terminal for 30 seconds then reattach it. That should do it for you

 

No i have not had time to check the fuse yet. But i was reading on another forum bout a similar issue with a few more problems and they were talkn bout some computer issue and didnt know if this would be a computer issue

 

most likely a fuse. check them and replace as necessary.

 

All those lights are on a single fuse.

Start simple before worrying too much
