Every Button Blows the Horn, Except One

YouTuber Levi Does Stuff was told his parents' car is acting up. He gave it a look and found that every button in the car activated the horn ...except the horn button! What does the horn button do? It starts the car, turns on the lights, windshield wipers, and blinkers, and probably calls 911, for all we know. I took a look around the internet to see if any forum was discussing this particular car, and found none, but I did find that people have been having problems with Buick car horns for years. Decades even. One has to wonder how this one was even driven home from the garage. I think they should take it back. (via Laughing Squid)
