My g35 horn won’t work

Hi, my 2007 g35 sedans horn won’t work and I’ve traced it down to either the clock spring or wiring from clock spring to the horn relay. I have no other electrical issues and all of my other steering wheel buttons work so I don’t think that it is the clockspring. Does anyone know what the wire color is from the clockspring to the horn relay and how do I find the break? I would really appreciate any help.

Interestingly, it seems you have two horn relays and two fuses #31 & #38. Check those first! Your horn FSM is here:
https://www.nicoclub.com/service-man...2007%2Fhrn.pdf
Below the window, "click here to download a copy".

It looks like that wire from the coil to relay 1 starts as green, then passes through a GIANT wire-to-wire connector (pin-41) and is light green beyond that.
Meanwhile, here's a pic of the diagram.

oh I see. Would you know the location of the second relay? I know one is in the battery bay in the relay box but where would the other one be?

The other book you might want is the "Power & Ground" FSM:
https://www.nicoclub.com/service-man...F2007%2Fpg.pdf
same thing to download a copy.

In there we find that those relays plug into connectors E11 and E18 which are here:
hope that helps

OP, you should just go up one level from these individual section URLs and download the entire FSM. It'll do ya no harm. Once you have them all in one folder, start with the FWD file. It's the bookmarked table of contents, and will take you to whatever section you want to check out.

I agree. Collect them all! Very handy.
