Anyone know what relay to use for horns? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

BRZlimited · 03-30-2014, 11:50 AM

I put in hella aftermarket horns and for some reason they aren't working now. I checked the fuses but those are fine. All the wiring is fine so I believe it's the relay. Thing is I'm bad with electric related things so I have no idea what relay I would need to get. If anyone could help me out with a Amazon link or anything it would be really appreciated. It's really nerve racking driving with no horns in a small car lol.

Did you check the horn relay ...... (see "horn" upper left - follow the line).

Yea I was able to locate which one was the horn relay but I have no idea how to tell if it's good or not. I'm assuming it isn't since both fuses are intact.

Well, now, the easiest way is to swap it with another relay and see if the horn works.

Which relay do you think would be the best to swap it out with? I don't want to mess with anything that shouldn't be messed with.

You dont need a relay, with stock fuse it works fine.
Double check your wiring

They've been on the car for a good three months without a problem, there's a stuck relay though. If the stock relay goes bad would that cause them to stop working?

you can swap relay with anyone that looks the same, heater, fan, drl.

you can also have your friend honk the horn and you feel for the relay clicking.
