Hey guys,

I have a 2007 350z and my rear right turn signal went out a few days ago and I checked and the only one not lighting up was the rear right. Fast forward a few days when I get new bulbs and replace that one and still nothing. I took the working bulb out of the left and tried it in the right and still nothing, the front right works completely fine as well as the both of the left ones, and that's where I'm kind of stuck.


This wouldn't be a fuse issue since the others are working just fine right? Is this likely an electrical or wiring issue at this point?

 

Start by checking for corrosion in the socket and then make sure that the ground on the one bad signal is good.

EDIT:
Sometimes if you use a heavy-duty aftermarket bulb on one side, it'll make the other bulbs flash quickly. Always replace both the signal bulbs in pairs and best to stick with OEM. Still, the first thing you should check for is corrosion and/or a bad ground on the non-functional socket.

 

I don't see any signs of corrosion and I can't really check the ground wire without taking the bumper off it seems, so I'll have to do that another day. Thanks!

 

You don't need to pull the bumper. You can get to them through the access port under the rear lights. Easy enough to examine the sockets and probe the grounds from there.

Here's a how-to:
