I've changed the bulbs and checked all the fuses(concerning lights and lamps)on my 04 G35 coupe and still no license plate lights.

 

if your not sure call the nearest infiniti dealer, they should know

 

Make sure the harness is plugged in behind the rear bumper. I actually had the same problem yesterday and found that the harness somehow shook loose.

 

did u switch the bulbs around, like + to - and - to +, if that doesnt work then i dont know

 

How do you get to the harness behind the bumper?

 

Can you tell me how to locate and get to the harness?

 

x2 on that note. When I replaced my bulbs with LED's they didnt work and I switched them around and VOILA!

 

^leds you have to mess with + and - but not oem glass bulbs..assuming that his bulbs are stocks.
I say +1 on wiring behind comin lose.

 

to get to the harness look up in the gap of your rear bumper above your license plate and you'll see 2 little plastic housings, on one side of each of them it's a bit longer and you sort of push it towards the lens and it should pop down.. sorry kind of hard to explain

 

i think it would be the main harness that connects to the splitter. Its a PIA to reach but its an simple problem. If you look underneath the bumper you can see the metal housing that the lights clip into. those lights are plugged into a 2 to 1 harness (it looks like a Y). You want to look for the main clip.
