Why does a click sound come from the opposite side of the car to the horn but the horn doesnt work?

I JUST had and fixed the same problem on my 2000 Jeep Cherokee. The fuse is blown, in the fuse box on the passenger side. I believe it is the 15 amp fuse #20 or #21. good luck!

My guess would be the horn or horn relay or connections between the them is At Fault. The click you hear would be the horn relay trying to work, that tells me the fuse and horn button is in working order. Unplug the wire at the horn and attach a test light to the wire. Operate the horn button and see if the light lights or not. If the light lights up the horn is at fault. If the light doesn't light up and you still hear the click I would replace the horn relay.
