Horn stuck on

Yesterday morning my truck was parked on the street with no one near it. The horn started blowing on its own and would not stop. I disconnected the battery and let it sit overnight as I was busy with something else. Today, I put the battery cable back on and it blows again. I have now pulled the wire plug from the horn to shut it up. Anyone experience a similar incident and have a solution? I suppose the relay might be stuck but it seems odd that it would have stuck on without being started. IE - I could understand if I hit the horn and it stayed on but don't understand it starting on its own. I'm thinking a short in a wire somewhere is more likely.

Truck is an 02 Supercrew.

You have a bad clock spring. You should also have other problems. Air bag light on? Good luck!

Is it hot where you are at, if so check the horn contacts.

No, airbag light is not on. Other issues have arisen today however. Cruise control appears to be dead and ac is not blowing cold. Also, maybe unrelated, but truck is idling rough and service engine soon light is on. Will check to see if any codes are available.

Not really hot here today but reasonably warm. Not sure what you mean by horn contacts?

I have had the horn stick on in the heat before. The pad where the switches are make contact from the plastic swelling in the heat. doesn't happen often but it can happen.
