It may be just a wiring issue, but they do die eventually and must be replaced.

Don't believe you pull battery and you get to the horns from underneath. Kinda behind or above the far passenger side front bumper. From underneath you can pull a rubber flap/plastic piece back to see the horns.

There are 2 horns, a high tone and a low tone. Don't get 2 of either, it won't sound right. You have to remove the bumper cover to get to them

This is what I used:

Low tone:

High Tone:

Only difference from OEM is the connector, sounds good.

I've seen nothing like Jons picture on either of my ZJ's.

I also can't find reference to the horns ever being under the battery in a ZJ from the factory.

Ima take them off a d spray wd40 inside and twirl em to get it in the center of the horn.. i read if you do that it can free up a rubber flap or whatever its called and possibly make the horn work again

I have replaced two horns, one on each jeep that I have had. Seems like an item that goes fairly easily
Before you bark up the wrong tree, make sure its the horn itself and not something else
You can access them from underneath the front corner of the bumper
Pick one connector and unplug it.
It will either continue to beep (you picked the dead one) or it will stop beeping (you picked the working one)
You MAY be able to go onto rock auto or a stealer and get a horn with that nice water tight connector
If not, a generic horn will work but you will need to crimp two spade clips to the ends of the wires
Since it is a 2-wire device there is no polarity, so its impossible to reverse + and -

On the last one I did the sheet metal nut that holds the thing in place went to crap
So I zip tied the whole assy to a brace under there
Turns out when the horns physically touch anything they sound half dead
I am going to pop a hole in the brace and mount with a bolt next time I am under there

Interesting . . . Mine is a '98 and original connector prior to my fix. The wires and metal ends were bad.
