Horn stuck on?

It was a rainy night yesterday. I didn't drive the Jeep in the rain at all, but it was sitting outside all night. At about 12:30 am the horn just came on and wouldn't go off. It was a steady blowing of the horn, like you just hit a tree or something. I turned the alarm off and back on, nothing worked. I got into the Jeep and started it and the horn didn't skip a beat still going off. I was half asleep and wanted to get back to bed instead of standing in my drive way in my underwear while it is sprinkling on me. I just disconnected the battery and went back to bed. Morning came, so I rode my bike and still haven't dealt with the problem yet, Battery is still disconnected.
I'm looking for suggestions as to the direction I should start looking into to find the problem? horn relay, clockspring, horn needs to be replaced, any tests I can do.

Thx fellas!!

He said it didn't skip a beat so I'm guessing its just a solid straight uninterrupting noise. I don't have an answer but mine has had issues before while driving. I pulled up to a stop sign one time full of people and my horn just came on by itself and stayed on for about 20 sec straight. I know people thought I was just being an *** but I tried to just hold my hands up in the air. Either way, I never figured out what it was but it finally stopped and has happened only once since then, that was about a year ago.

Could be anything really, something could be messed up with the pos/neg wire to the horn.

I would just take the fuse out. Im pretty sure there is a fuse for the horn. Pretty much every car has one just for the horn.

Yeah, it is just a steady hooooooooorrrrrrrrrnnnnnnn blow. I got home from work and connected the battery back up and unlocked and locked the doors with the remote and it seemed fine. later that evening i went out to the store and locked the jeep as i walked away from it and the horn beeped once then just started going off again. I walked back to the jeep unlocked it and popped the hood and disconnected the battery. When i came out of the store i connected the battery and all seemed fine, but just for good measure I pulled the horn relay. Of course the next day I get behind someone that doesn't go at a green light and I have no horn to blow........ so I yelled but their windows were up. so I sat thru the light again! gotta love it!
Anyone think it might be the clockspring? I have no lights or codes to tell me anything.

If your cruise works then it doesn't sound like a clock spring. Doesn't your clock spring supply the power to your steering wheel?

Cruise seems to work fine.
Would it be the horn is trying to tell me there is something else wrong? Has anyone ever had the relay on a horn go bad?

Here is an update.
It has been a while since the horn problem came up. I still have no engine codes telling me anything that was not working correctly. I have since put the horn relay back into place and haven't had a problem out of it since. Go figure!
Another werid one: The other night I was out late on my motorcycle and when I came home and was putting my bike away and noticed that the jeep turned on its headlights for about 2 secs, while the alarm was still on and the red light was blinking on the dash and then turned the lights off by themselves. My wife just said I must have some kind of connection with the Jeep. I have no idea, anyone else experience this?

Ya know, I never did.

But I'm going to say the horn thing might be attached to the master windows control and door locks on the drivers door. Cause I still the an intermittent problem with the interior lights not coming on when I open the door. I have already replaced the door latch with a new one and nothing changed. Sometimes the door might think its open and cause the horn to go off..... Idk I'm guessing. Only happened that one time. I have also noticed that if the passenger windows controls aren't lite up then they have lost connection with the jeep and the remote fob won't work. I think that goes bask to the drivers side window controls.
If u have an idea throw it at me at this point i will try anything. I'm just happy I have no trouble codes.

Definitely sounds like a short to power. If you know how to read a wiring diagram, heres one. I know it's not everything, but it might help get you started somewhere on finding out where that short is.
