So I'm sitting in my room and I hear a horn blaring. Its like someone is just holding their had on a horn and not letting go. My dad was in the bathroom and says its one of our cars outside I told him it was outfront he said its outback its one of ours. So i walk out to fine my car sitting there with the tail lights and corner lights on and horn blaring. My light switch was off i hit the steering wheel and nothing tried to start it and nothing. So i figured pull the battery. As I was walking away the horn just stops but the lights stayed on. I ended up pulling the batery to get the lights to go off anybody ever have this happen? Or know WTH is wrong with it?

) and fiberglass it with bondo fiberglass and when I get the ass end painted have them hit that too
