So I just bought my 03 G35 Used. Everything was fine. It rained today. Now my right blinker will blink ONCE aswell as flash the sidelights. Then stop. How ever if I turn the fog lights on with the inside indicator will blink fast but outside the light just stays on. Sometimes as I roll through the settings it will blink but sometimes it stays at normal speeds and just kind of fluctuates from fast to slow to normal

Because you mention rain you should check the passenger footwell to be sure you are not taking on water from the infamous sunroof drainpipe leak. If the BCM mounted in that in that area gets wet all kinds of weird things can happen.

 

Soooo I fixed it? Kind of? I turned my headlights on and hit the right turn signal.... it started blinking fast and the rear light was just one without blinking. So I then switched it to the left side turned the headlights off and switch back to right, now it works. ??? I think I unlocked a cheat code idk. I wonder if this has something to do with the Spec D headlights
