2016 Silverado 5.3 horn not working

[nluchau]

Got to work this morning, pressed the lock button on the key fob twice and horn would not sound.  Tried again and still the horn would not sound.  Is there a known problem with horns not working? It has been rather cold lately with below 0 temps for much of the last couple weeks it seems.  

 

Thanks!

Can you get in the truck and press the airbag, will the horn sound? Also, if any doors are slightly left open, the horn won’t sound when you try to lock the doors.

If it has stopped working just put a big ole air horn on the truck. That should work just fine

Mid day I went out and the horn sounded from the airbag and from the remote key fob when locking.  Weird.  It did get up to 6 degrees today so....  Doors were all closed.

Horns give out when cold too. I notice only my high tone horn would sound when it was only 12 degrees out

I have never heard of temp creating a problem with the horn, unless you have some bad wiring exposed and shorting out.
