Horn blows when it wants

I searched 6 pages of threads with the word "horn" it them and couldn't find anything close to my new problem.

My daughter came home and said "dad, my horn just went off without warning when I was driving home" I said "did you push it to make it stop?" and she said "no, it just stopped by itself after a few seconds".

So I passed it off as one of those things that just happens every now and then but...

We came home this evening after being out and the Jeep was just sitting there in the driveway with the horn blaring away. I don't know how long it was doing it but it couldn't have been too long because the battery was fine and the neighbors weren't out in the street gawking and now cops.

It's a 95 with an all stock steering wheel and horn. Any ideas what would make it just go off? All I had to do to get it to stop was press the horn. It seemed to have plenty of play at the button and I took the cover off and couldn't see anything broke or amiss.

I am at a loss.

Any ideas?

Mine was doing the same thing. I took it apart and noticed one of the spokes on the steering wheel was cracked and causing it to flex and make contact.

Try hitting the steering wheel with your hands to make it shake, see if it goes off. I had a similar problem with my XJ, (under the horn cover) the three screws that held down the green plastic ring were loose, causing the metal dome (popper for lack of better term) to bounce around and ground out.

how many jeeps do you have to have to be considered a collector?

my 90 had the same issue. I don't know what your steering wheel looks like but mine had a center button (no airbag) I pulled on it and found out the flat spring in the center of the steering wheel broke and the two contacts could touch given the right angle and phase of the moon. It was an easy fix.

pull off the rubber cover and take out the 3 screws and youll see a little nub sticking out underthat is a small spacer and under that is a tiny spring. If u dont see the spring its possible that its bouncing around in there grounding itself out causing the horn to go off randomly.

I would say the look the same. IIRC air bags didn't come in until the 97 TJ's. I will take a look at this tonight.

I am not sure what spring you are referring to. Do you have a picture?

I didn't think any YJs did. Just using the airbag thing as an size indicator. Never sat in anything yj newer than mine and didn't know if there were plastic covered spokes on the stock wheel .

Airbags were not standard on YJ's. Although they MIGHT have been an option in 95.
