Horn honks when turning, randomly

fix unlatching and alarm gets happy?
find why the latch fails.
this will take close inspection of the latch. and its controls.

There is a short on the horn circuit

The battery is most likely gone dead

Disconnect it & have it tested over the
next couple days

This is a clockspring issue that you should repair. If the clockspring is honking the horn, it may next inflate the airbag. You don't want that to happen!

One honk means all doors are closed. Door ajar you have 2 honks telling you a door is open. My 03 Explorer has had the door ajar light on for awhile

its possible that the relay is the problem as most relays have a second power feed wire,if it shorts to the horn side of the relay it can blow the horn.doesn`t happen very often but it does happen.this could explain the horn blowing without the fuse in.you can get a door key made at a lock smith to solve that problem.

THE SWITCH IN THE STEERING WHEEL IS PROBABLY GOING BAD OR HAS A LOOSE CONNECTION THAT IS GROUNDING OUT AND COMPLETETING THE CIRCUIT AT RANDOM. I REALLY DONT KNOW HOW OR WHY SHUTTING IT OFF WOULD TEPORARILY FIX THE PROBLEM BUT WITH ELECTRICAL PROBLEMS ANYTHING IS POSSIBLE BELIEVE ME. ALSO TAKE A LOOK AT THE WIRING AND THE HORN ITSELF TO SEE IF EVERYTHING LOOKS OK THERE.

Just take out the horn fuse. Your Horn Pad is bad.

The steering wheel needs to pulled off, there is a short somewhere in there. Better have it done, cause if it isn't done right, the air bag can deploy.

obviously there is a short in the system probably in the wiring and likely it is exposed wiring. Motion,moisture, and heat would then effect the wiring and cause it too short out at different times and for varied lengths of times. driving your car would cause it to get hot under the hood, so after awhile the wiring shorts and your horn honks. Turning on and off the system causes motion and if it is stuck in a particular position when it shorts than the horn continues to honk
