A while back I wrecked my caliber into a ditch. Ever since then the horn has not worked. As far as I know there is no power going to the horn but the fuse is just fine. I was wondering if its possibly the relay and I don't know where the relay is. I've been trying to find info on it and couldn't get a hold of anything. I have a car inspection coming up and I just wanted to get this fixed in case they ask about it.
