I just got my first G35 - an early 2003 model sedan. The miles are low 66,000 and the car is clean. It has spent its entire life in the salty north so I may have crusty connections somewhere. My side and tail lights have only come on once so far that I have seen. This lasted 5 minutes and then they went out ( the key was not on at this time and maybe the lights went into some sort of sleep mode). I am using a coup FSM. I assume the body electrics are the same. Is the fuse and the tail light relay located behind the battery (remove battery to access)? Is this a common G35 problem? If so what is the fix?
Any help would be appreciated.

 

if im reading this right, it just sounds like a wiring issue... huge PITA, you're just going to have to start with the fuse, then if thats good get a meter and start checking wires.

 

As I am new to Infiniti I did not know the fuse and relay for these lights is located under a panel on the fire wall right side next to the battery under 2 removable panels. Once found, troubleshooting was basic. The culprit was a corroded side marker socket causing the fuse to blow when I moved the lighting wires around previously.

 

makes sense. i'd say you got lucky. a friend of mine had a rat living in the firewall of his 03. not pretty what happened there.... any wiring issues in just about any car would cause me to turn and RUN.

 

Welcome to G35Driver. PM me and I'll send you a 03 sedan FSM. (I have an 03 as well)

 

Oops. Just found this... they're already available here:

Thank you but when i tap on that link it says 404 not found,
you think you can give me an anwser that will actually help me out?

 

Did you replace fuse 71 located in the IPDM (engine bay fuse box next to the battery) it's a 10A fuse, do you have ANY parking lights on the vehicle, license plate, side marker, front parking, rear parking, are they ALL not functional? If you have NOTHING then it's likely the relay which is inside the IPDM and I believe is a non-replaceable type. It's also possible your BCM is going out since it sends the signal to the BCM over the CAN to operate the relay.
