Anyone have an idea why my ride honks at me from the driveway? Is it lonely? But seriously, my '04 cummins 2500 has a random horn honk just sitting in front of the house. It even did it when I was visiting friends. Doesn't matter if the doors are locked or not. I have the stock security system. I shut off the honk feature when locking the doors and it still does it. Luckily the horn has it's own fuse. It doesn't honk right now, but that silences the security system.
