Horn not working

My horn is not working. It's a 95 YJ 4.0. I don't even know where to start trouble shooting. I cannot live without a horn.

A common problem. Often the the contact ring under the horn button is rusty so good contact can't be made. Pull the horn button off the steering wheel and check. If rusty you can just wire brush it off and coat it with WD40 or any other anti rust liquid. I f this isn't it check your fuses and grounds. But I'd guess it's just a little rust.

Heres a quote from another thread on the subject.

To get to them pull off the "horn button" (the center piece in the steering wheel- it should pop right off) once inside you'll see round metal piece that had held the center cap in place.
Within that there are three phillips head screws. Unscrew those and pull it off with the plastic green ring (it's there to align everything in there correctly)
under all of that there will be a thin metal ring. This is the actuall contact plate that completes the circut for the horn.
If either of these pieces is rusted thats your problem. clean off any rust and put it all back together.
Oh yeah before you do anyof this make sure to unplug your horn or else it will be going off randomly throughout this process.

That would be a quick fix if it's the rust. I'll have to check that once I get home. Thanks!

When you pull the cap off there are 3 phillip head screws holding the center push on then 3 small screws holding the insulator to the wheel. Theres a pin and spring under the round slotted thin plate so be careful when you take the first 3 screws out it will go flying. Ask me how I know lol.
To make sure the problem is in the steering wheel push the pin and screw to the side to make contact with the metal and the sleeve that the spring sits in, if the horn blares then you know its do to the rust there.

I can do this without pulling the steering wheel?

Stupid question but did you check the fuse.. If I am not mistaken the horn and brake lights are on the same fuse.I did not confirm this but instead I am going off of memory.

Also, suggest you check the wire connection to the horn in the engine compartment. It may have slipped loose like mine did, or it may have corrosion on it and not make contact. My horn is on the fender well below the hood, driver side.

Mines in the same spot. I will have to check that too. Thanks for the heads up.

Check for a good ground to the horn. A weak or inconsistent ground will give a non-effective or weak horn.

Is it bad that this simple fix has not been looked into by me yet? I've been using my loud pipes as a horn since I bought the heep...

I'll be looking into this when I make it home tonight.

I will also note that when I was repairing mine that once I had it all apart and cleaned put back together it still wouldn't work. I took it back apart and with the pin pushed against the spring touched the pin to the metal slot in sits in and it would work. Put it all back together and again not working. Bump the steering wheel real hard side ways and it started working,,lol Yea the old saying if it doesn't work with a gentle touch break out a BFH.. there was a loose connection below the wheel to the contact and guess it needed a lil wake up call. Worked fine since..
