Does anyone have problems with their Ranger's horn honking by itself? It did it 7 times the other day while on an extremely busy freeway in SF Bay Area. So scary to try and get to a shoulder or exit so I can shut the truck off and wait for it to reset. It doesn't honk every day; it's intermittent. Ford Service here in Sonora has no idea what's wrong since there are not codes or how to fix it.
