I installed a carbon fiber led steering wheel. Installed it once and broke a piece of trim. So had to take it off and reinstall. This time everything looks good but horn is not working. Dealership refuses to even look at it. Any ideas on cause?

Number of things are possible if it's not simply just a issue of a loose connection. It'll be hard to say for anyone here, you'll need to get it checked out in-person.

Does the horn work with the OEM steering wheel?

[Asmooth0101]

Horn works when I press it from the app, so it’s not the horn itself that is bad.

It’s something about the mechanism or switch but I don’t have any sight into how the horn actually works

Was curious if anyone else does

Check all connections. Reinstall old wheel, test honk. Reinstall new wheel, test honk. If it’s not working then the new wheels may have a defective part or wiring.

Fuse?

[Asmooth0101]

My thought was that if it was the fuse, the horn wouldn’t work from the app either. But it does. So I’m thinking it’s a connection issue.

I figured it out. I have the same issue. The horn is actually still working. If you take the airbag back off and you push in on the ring where the horn is, it will honk, but for some reason the airbag is not contacting and allowing it to honk, anybody have any ideas on how to fix this or what the torque setting should be on the three screws that hold the horn mechanism in place?

Can you take a picture of the horn ? I have no clue what it looks like with the airbag off

It’s the silver thing with the three screws holding it in place and it’s sitting on 3 springs.

Im think I ivertigjtened those screws. BecUse the first time I installed it worked

And this time, I definitely tightened them more because the airbag was sticking out a little before

[Callen4827]

I tried loosening it and it didn’t work, I think it needs to be tighter as the top part works after tightening but I think I still need to tighten it more.

[Asmooth0101]

Let me know if you figure it out. Would appreciate any insights

[Callen4827]

I’ll probably mess with it over the weekend

[Callen4827]

I actually just went out and checked on it and it’s definitely something to do with those three screws being screwed in the correct torque settings. I got the top part the horn to work better, but the bottom part still needs to be played with, but I’ll mess with the more over the weekend.

[Asmooth0101]

Getting the damn airbag off took me hours soi am very reluctant to try again but I need the horn to work!

[Callen4827]

I used a torx screw driver because it’s flat on the end. A regular screw driver is a pain and you really need that flat end. There are a few videos on YouTube that show you how to pop it off. I can do it in less than a minute now.

[Callen4827]

Are you near Washington DC? I’m in VA near there so i would be happy to help with the air bag

[Asmooth0101]

I am! In Bethesda!

[Callen4827]

If you need some help, let me know. You can come to my house and we can get it straightened out. Message me and I’ll give you my cell #.

[Asmooth0101]

Awesome. Thx. I’m away for vaca for 2 weeks but will hit you up when I am back. Much appreciated.

[Callen4827]

No problem

[KANdaddy]

I mean, do any of us really use the horn anyway? 🤷🏻‍♂️
