Horn stopped working

Hi, We have a 1994 Grand Cherokee and the horn stopped working. I replaced the fuse (20 amp) and the relay (under glove box). Still click, click. I took the horns off and took my test light and touched the connector wires to the horn and when the horn is pushed the test light comes on. So I have power to the horns. I took both horns and took them to my bench wire brush to get all the rust off of them. I took 1 of the horns and touched to the battery and it blew. The other horn I had nothing. I tried touching the good horn (I thought) to the battery later and nothing. Do you think I blew both horns at once? Or do you think its something else? I hooked them back up after all of that and still click click at relay.. Thank you

You have power to the horn, you tested them on the bench and they both failed....

I'm gonna go with the horns are bad.

I really doubt that both went out at the same time tho...I would say one stoped working a LONG time ago, the other one worked and you never new the difference untill the other died also.

And, you have a ZJ, not a XJ. But for a horn problem there is no difference in the wiring.

X 2, Any other explanation would be dealing with the supernatural!

Just do what I did, get a horn relay and wire in a switch to the cabin. It was actually cheaper than getting 2 new horn units.. lol. $36 to get a cheap air horn kit from Hella.

How does the relay and extra switch help?

or i know harbor freight sells all types of air horns that can be easily wired and mounted in an hour or so. and if your geting power to the horns you can just tap the air horns off the old horn wire so you dont have to install any switches.

i have 3 little air horns and the stock jeep horn. but idk about xj's i know in my yj thare is plenty of room for a small horn like this.

I did the HF air horn thing in the K5 I used to have but I tossed the relay and ran a power wire straight from the fuse box to the air compressor and ran the ground through a B&M shifter knob with a momentary button on it. It was badass, might be worth you considering but the knob was a little pricey
