Ok my horn worked when I picked the truck up. Today it stopped working all together. Both when I lock the doors with the remote and when I push the horn from the steering wheel.
So I called my salesman this morning so I can bring it in monday. All day the horn doesnt work, I tried it a million times. THen it starts to work on its own.
So I call the dealership again to tell em that it works and I will call if it goes out again. No sooner than I hang up the horn doesnt work again.
Pretty sure there's a relay for the horn. Most likely that went bad or it's not seated correctly. Also, check the fuse...the wires might have shorted out somewhere. And last, the contacts in the steering wheel, or the harness through the column, might be bad.
