Welcome to CF from Tj... Try checking the horn first with a volt meter and then the relay under the hood. I don't know exactly where it is but Ill do some research and post it...Tj

I found this answer from just searching on YAHOO SEARCH

Try it an let us know if it works. THen if you could post a pic of the relay for everyone else.

Thanks

I burned out the relays for my horn and initially thought it was just the low horn, because my high horn would work. But after swapping in used horns from the junkyard and not getting a response, I went searching for the relays. I didn't know what I was looking for because my unhelpful Haynes manual did not clarify where to look, and the wiring schematic is useless at best. Although I'm glad they took the time to explain where my speaker wires are.
Anyhow, some websites say that it's a 3 prong relay, others' say it's 2. Well I kept hitting the horn button and could hear the clicks. I located the 2 relays to the right of the steering wheel, bolted up to a black bracket which is screwed to the lower dash with two screws. The relays have these numbers on them, on separate lines. 56006709/50732/116182. The pin outs on back have 30, 85,86, 87,87. The relays are black and they don't say horn relay but with them disconnected, I don't hear any clicking when I hit the horn button.
If you need to replace your horns, there is a flat style nut that holds the horn to the bracket, and the bolt that holds the bracket to the chassis is 1/2", but for all I know it's metric like the rest, I just found a 1/2" wrench easier to use. You can access the horns from underneath the Jeep by pulling back the flap that is underneath it. It's part of the fenderwell innercover, but all you need to do is tug at it towards the tire.

i took a look under the dash and did find a group of relays, but they look difrent then the one my auto parts store gave me.

the relay they suggested

XJ Stryker

I would drive up there and then buy the one that fixes it. There have been a lot of times I have picked up something for the XJ that the auto parts store gave me and it turned out to be the wrong part.

there are 3 spots there and there is only one relay, should i get a new one and just try all 3 spots? are they all horn relay connectors?

XJ Stryker

I dunno your guess is as good as mine.
