Could it be the horn relay? Maybe grab a same sized relay( fuel pump I think is the same) and swap them to see if the horn works. Make sure to swap them back tho so your jeep will get fuel if it was a bad relay.

The fuse block is located under the left side of the instrument panel next to the parking brake.

Yeah under the hood is the fuse box and relays. You don't need a meter but one would help. On the fuse box lid it should say what each fuse is. Locate the horn one, pull it out and look to see if it is blown. The lid should also tell you what each relay is. If the fuse is good, check to see if the relay is bad by swapping it with the same size relay. Replace the one you swapped out if your horn works now.

The first is the fuse box. The second is the lid showing locations and the fuses and relays.

When you press the horn button , have someone listen at the relay .
You'll hear it click . If not change relay , still no click issue is upstream

Gone through any deep water or mud lately? I thought mine went out but it was just filled with water which only let a little sound come out that you couldn't hear unless you had your ear right next to it. I shook water out of mine when I took it off and then let it air dry for a week and it should work again if that is the problem.

Power is fed directly from Fuse 20 (20 amp) in the PDC to the horn relay in the PDC. The coil circuit in the relay is completed by grounding the yellow wire in the steering column, which closes the relay and sends power through the relay and out the red wire to the horns.

Fuse 20....> Relay Coil...>Horn Switch....>Ground
Fuse 20....> Relay Switch.....>Horn.....>Ground

It either has to be the fuse, the relay, steering column switch or a connection, or bad ground.
