If all else fails the diaphragm in horn may be stuck (common problem ), hit it with a hammer, not too hard to break it tho....
Horn not working
- Thread starter JeepDew
- Start date
Throwing money at a problem is certianly a method of troubleshooting but it can get expensive. Jerry is 100% right IF the relay is working the problem must be down stream of the relay...i.e. wiring or the horn itself. Take the horn out and connect it to the battery and see if it sounds. If it does the problem is in the wiring.
OP
UPDATE: I just went outside to confirm that what I heard was clicking at the relay.... conclusion is that I need to stop drinking beer while working on the Jeep....
No noise from the relay, even switched relays with no success.
From Jerry's post the fuse is in position 18 in the PDC.UPDATE: I just went outside to confirm that what I heard was clicking at the relay.... conclusion is that I need to stop drinking beer while working on the Jeep....

UPDATE again... went outside... found the blown fuse just like Jerry's diagram.... here the new problem.
put in the new fuse, horn won't stop beeping
and not sure if its related... the windshield wiper fluid won't spray now...
Lets first fix the horn, then worry about the windshield wiper fluid

Now try swapping out horn relay, contacts inside may be welded together.
Report results back.
Then we will go from there

I did switch relays also, same result... horn just beeps, can it be the contact in the steering wheel?

Yes, with steering wheel removed connect your meter ( set to ohms) probe the 2 wires to horn switch, report back with readings.

"we did the meter... noactivity at the horn"
Thought you had one...if not, time to buy a cheapie.
Especially if you're a Jeep owner

I should not have said remove steering wheel, what I meant was horn switch/airbag unit.
Sorry for misinformation

Really? If you remove the fuse will the wiper fluid pump work again?

no, we discovered that the horn and the wiper fluid aren't working.... now just have to figure out why the horn keeps beeping when I put in the new fuse....
OP
you mean if I unhook it at the steering wheel does it still beep... not sure but will check.

Look at picture post number 15, when you have this disconnected.
With new fuse in does the horn still blast noise?

have not tried that... will look into that this weekend. Will keep you all posted. Thank you
Probably in the steering wheel. I drove my MJ for 9 yrs with no horn. No big deal, no hardship. Horns don't blow away whatever you're honking at ahead. But I also don't like things that don't work.
