2016 horn working but only high-pitch

[ryams27]

Hey guys,

So several weeks ago I noticed that when I accidentally set my car alarm off, the horn sounded funny. Almost like it was "hoarse" or dying or something. The pitch sounded relatively normal - it just wasn't a "full" sound if that makes sense. I, knowing nothing about anything, thought maybe it was because of bunch of leaves were between the hood and windshield or something. Stupid, I know.

Fast forward a couple of weeks and I'm driving down the road and someone pulls out right on top of me -- I hit the horn and it seriously sounded like a clown-car horn. Really high-pitched and puny. It's continued to sound that way ever since, whether I honk the horn or lock the vehicle with the fob.

I've read elsewhere that there might actually be two horns that combine to make up your horn sound -- a high-pitched one and a low-pitched one. Well, assuming that to be the case, my low-pitched one is clearly not working.

I managed to educate myself on how to check the fuses and confirmed there isn't a fuse issue (at least not one that I could identify).

Anyone have any ideas what could be going on? And/or what steps you would take to try to fix it?

Only a single horn and you need to pull the driver's side front wheel well liner down to get at the horn.

Verify you have power (and proper voltage) at the horn on the voltage supply wire(s)
Verify you have good continuity between your horn and the ground (frame) of your truck.
Verify your horn didn't get packed full of road debris or has physical damage to it.
Also check for water damage to the horn or corrosion in your wires / connectors.

Horns are relatively cheap and you can upgrade them and do the whole job in about 15 minutes. It might be worth buying a new horn and just plugging it into your truck and testing the sound.
