This morning while I was getting ready to head out for work at 4 this morning, my horn decided to go off! Not the panic horn and flashers, but as if someone was holding their hand on it. Tried starting, and activating the panic, and locking/un-locking doors with no luck. Just popped the hood and disconnected the batteries. We did have a little rain last night but its been in worse rain storms than that without any issues. Will trouble shoot tonight when I get off work. Has anyone ever had this happen to them?
