Not horn volume, actual horn not working. Here is what I checked:
power to fuse panel
power to coil
power to common point on relay
independent test of relay
+12 V to NO contact of fuse block makes horn work

It's as if the relay is not getting a signal to close the coil in the relay. Started noticing that the horn beep was sporadic when locking the door. Now honking the horn does nothing. Setting off the panic alarm only flashes the lights.

Any ideas? Anyone else experience this?

It’s karma for you locking the doors with the remote. Use the door switch and stop pissing off your neighbors! But seriously, if it’s i
Under warranty take it on. Good luck.

What do you need a horn for?.....😂

Do you Check the horn direct to 12 volt??
Sometimes the horns simply fail cause water, etc

If the alarm works, then the horn works (not defective).

I hope it's not the clockspring

I lock the vehicle using the button on the door handle, used to get a confirmation beep. Now nothing. It's a '16 so out of warranty.

If I put +12V to the pin on the relay (NO contact), the horn sounds.

I hope you get it sorted out. Best wishes.

Update,

I found what appears to be a FSM online and used it for more troubleshooting. But at the end of the day I didn't do anything. I was going to have to bring it in on the next few months but wanted to try and fix it myself.

Went for a drive and did the 1970's TV fix. I smacked the horn button a few times in all the corners while on a quiet road. The horn started working!! Maybe pulling the relay, fuses, and smacking the crap of the horn button cleaned the contacts. Even started working when locking the doors with the button on the door handle.

When all else fails, get a bigger hammer!
