Horn not working

Ok here is the update.... took the Horn/Airbag unit out. changed the fuse with no beeping. I laid the unit back in the steering wheel opening and the beeping began again.... Has something to do with when it touches the steering wheel metal bracket.

Any and all ideas are greatly appreciated.

Thank you

I am having the same issue with my switch. Changed the fuse and clock spring a few months ago and now I have air bags but horn will not shut off. I have the actual horn disconnected at this point. Will pull the airbag center cap from the steering wheel this weekend and see if I can rig the switch somehow. The pic above really helped me to understand what i was looking for. I figure I was about to order a new airbag center cap anyway so if this doesn't work, then no harm. Will report my success or failure next week.

Hello. I see ‘this is an older post. Was there any success with fixing the horn switch in the air bag center cap. I traced the issue up to there. I want to take the bag out but I don’t want to mess the bag up. Wanted to know how it turned out. Thanks.
 
Fixed

I too had the horn not working problem. I had a bad relay, changed it everything worked. A few days later no horn blown fuse was the problem. Changed the fuse then a couple days later horn was blowing on its own. Did more research went to a junk yard swapped my horn for a caddy horn and no problems in 5 years.

Do you need to disconnect the battery to access the horn wiring in the wheel? My horn relay is working fine (swapped around), but does not click when I press the horn button on the wheel
 
Narrow it down the old school way:

First remove the horn and test it directly into the battery
If that works, then test the wire for power (buy a chepo walmart kit)
If that works, the steering wheel horn wire needs to be looked at
If that works go to your fuse box
If the fuse is intact, you gotta bigger problem my friend :)
What do you mean by bigger problem, because I’m afraid that’s what I have.
 
I was just reading about the problems jeep dew was having with his horn..... luckily he posted a picture of what the horn/ switch piece looks like. It's. Membrane and it looks like a little bag with a positive and a negative wire. This switch is like a little bag and is filled with some type of gel that when pressed from the outside it causes the gel to move out of the center of the little bag therefore making a connection . When this gel drys out causes both membrane walls to touch each other and continuously activate the horn. This piece is the problem. Always the problem . Replace this membrane looking thing and problem solved. Nothing else is wrong just this piece. Contact your jeep dealer and get it new. Do not trust an used from junk yard.

when horn doesn't work this is your reason
when pressing horn from outside and nothing happens this is your problem
when horn comes on by itself and doesn't turn off until you remove fuse this is your problem.
when turning wheel and horn activates you might be pinching this wires.
 
Hey JeepLiberty202! You identified my exact problem. Thanks! I honked at my granddaughters yesterday in my 1997 TJ and horn wouldn’t stop. Had to pull fuse. Were you able to replace just the horn switch membrane versus the entire airbag/horn switch assembly? If so, where did you find the membrane switch?
 
My Horns not working either. My relay clicks when I depress the horn. So I’m thinking the issue is from the relay to the horn. The fuse is good and I tried to switch relays with fuel pump and still no luck. I put a test light on the negative side of the battery and and tried to get a signal at the horn connector with no luck. I switched over to the positive and got a good signal. I keep reading about a ground (G102) but can’t find where this ground is located. I’ve also taken the steering wheel cover off and verified connections are intact. Any advise would be appreciated.
 
What year is your TJ? Your Profile is empty, that's where members go to find information about the Jeep someone is asking about... model year, engine size, transmission type, etc. The model year is important due to the possibility of wiring colors changing between model years.

And a big welcome to WTF! :)

Sorry, it’s a 99 with the 4.0L and 5 sp manual transmission.
 
Put a volt meter on the horn connection with the white wire with red tracer leading to it. Ground the meter's - lead to any bare metal spot. Have a helper push the horn button and see if you get 12 volts to that lead which should appear when the horn relay engages. If you get a solid 12 volts there, check the horn's black ground wire with the meter's Ohmmeter function to see if it's connected to ground as it should be.

With the horn relay clicking, the horn button is working fine. If the horn is getting 12 volts and the ground is connected to ground but doesn't sound, the horn is bad. If it's missing the 12 volts or ground, check the black ground wire and red/white wire that connects to the relay at its other end for problems.
 
Have someone repeatedly push on the horn button while you listen to/feel the horn relay. If the horn relay is clicking that verifies the horn button is working. If the horn relay is clicking that means the problem is between the horn and the horn relay. If the horn relay isn't clicking the problem is between the horn button and the relay. Swap the horn relay with one of the other relays too, it's possible (though unlikely) you simply have a bad horn relay which is located inside the Power Distribution Center in front of the battery.

ya thats what mine was too.......

After checking with meter, I have 12.6 volts at the red/white wire on the horn connection. I’m no electrician but I tried measuring ohms but I’m not 100% certain I was doing it right but measured 1.3 on 200 ohms setting. (Attached pictures) It is also a dual horn setup from the factory so I checked both and got same. Also when you say check black ground wire and red/white wire at other end, are you referring to where the relay module is at, in the fuse/relay PCM? Again thank you so much for the help.

Since you're getting 12.6v at both horns, they're either missing the ground or the connection at the connector closest to the relay is bad. Pull that connector, closest to the relay, off the horn and take a good look at how the wires connect to it.

The wires come to one horn's connector first and then go on to the second connector. The connections at that first connector should be closely examined
