hugoh84 before replacing the horn button I suggest that you also check Fuse #13 in the fuse block as well as the relay and the horn itself. This from the service manual:
"HORN RELAY
Inspect 20 amp fuse, #13, located in the Fuse block.
Replace fuse as required.
Depress Horn Switch. The relay contacts should click. If ok, go to HORNS. If not, go to next step.
Remove relay (BLACK) from the relay center located under the glove box (Fig. 5). There should be battery voltage at cavity 1. If not, repair open in circuit to relay.
Depress horn switch. Measure resistance between relay cavity 2 and ground. The meter should read zero ohms. If not, repair open to horn switch ground.
Measure resistance between relay cavity 4 and ground. The meter should read almost zero ohms (horn resistance) If OK, replace relay. If not, repair open in circuit between relay and horn.
HORN
Measure the resistance between the horn connector pin B (black) and chassis ground. The meter should read zero ohms. If not, repair open to ground.
Disconnect horn connector. Depress Horn Switch. There should be battery voltage at the horn connector pin A (dark green). If OK, replace horn assembly. If not, repair open to relay.
If you really want to mess with the switch, here are the instructions for that:"
HORN SWITCH REPLACEMENT
WARNING: BEFORE BEGINNING ANY AIR BAG SYSTEM COMPONENT REMOVAL OR INSTALLATION,
REMOVE AND ISOLATE THE NEGATIVE (-) CABLE FROM THE BATTERY. THIS IS THE ONLY SURE WAY TO DISABLE THE AIR BAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIR BAG DEPLOYMENT AND POSSIBLE INJURY.
(1) Disconnect and isolate the battery negative cable.
(2) Remove 4 retaining nuts from back of steering wheel. Remove air bag module.
(3) Disconnect wire from rear of air bag module.
(4) Place air bag module on a clean level surface with pad facing upward.
(5) Pry out 2 trim cover buttons on back of steering wheel to access retaining screws for the horn switch.
(6) Remove 2 screws and disconnect horn wires located in the lower portion of steering wheel. Push wires through the access holes and remove horn switch.
(7) To install, reverse the previous procedures. Use caution not to pinch wires.

Could this be the same for a
96 Jeep Cherokee sport?.
I can hear the horn clicking. But I can't find any bad wiring or fuses Or relays
@ottedakota2011 sure it could be. what are the issues with your Jeep?

Hi @Wilburn Jones,
Just to help (or maybe confuse you even more, apologies if it does) here’s a link to the horn section from the 1997 Jeep Cherokee repair manual. I realize that you said 1998 (or perhaps 1996?) but maybe 1997 being inbetween may provide some answers ;-)
Here’s a link to the wiring diagram section of the repair manual which includes the horns.
Here’s an image taken from the wiring diagrams showing the circuit details.

To make it easier to read the manuals, download them to your computer. Just click on the download icon, to the right of the Zoom 100% at the bottom of the document window.

My 1998? Grand Cherokee fuse block 13 near the floor in front of the passenger door is 15amp “Hazzard” so this does not sync? My horns will NOT shut OFF unless the relay is removed from the power center above the right front fender. It is not under the glove box as you are saying? This is why I am guessing that the horn switch in the steer-ing wheel is defective (locked in the contact Position causing the permanent Ground. -I have NO Cavity reference numbers on the relay cavity or on the relay shell. therefore I’m unable to Measure OHMs or Volt as in your instructions. I’’m questioning IF my Jeep Door stating Manufacture 7/96, though title as the 3rd owner reads 1998 the door may have been replaced from a salvage yard? Thanks for giving the instructions for replacing the horn switch in the steering wheel.
