Tip & How-To about 1992 Jeep Cherokee Sport

Locating horn relays for 1992 Jeep Cherokee Laredo

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.

Car horn wont work. Dont hear the relay clicking. Does anyone have any suggestions?


If the fuse blew, most likely the new one you installed also blew. Check it again. You have a short somewhere. Double check all the wires you did while installing the horn button.

Horn not working


or it is the horn, and that has gone bad. Could also be low voltage getting to the horn.
You should have a relay separate from the fuse for it.
Find that relay and swap it with another one of the same size.
like, if the power windows or headlights are the same part number for the relay, just switch them for the test.
if the relay is not the problem, and the horn itself is a no go, the problem could be in the steering wheel/horn ring. under the airbag.

hope this puts you on the right track

The horn will not work on my 96 mercury grand marquis. The horn makes a sound when locking the door with the remote keys, but it will not work when pushing on the steering wheel. I've checked both the horn relay and fuse, both are ok.


Your horn contact in the steering assembly probably uses what is called a 'slip-ring' type contact and the 'ring' which is part of the steering wheel itself may be contaminated or the stationary contact, which uses low-pressure spring material, is either worn or the spring has grown weak. You will have to gain access to the inside of the steering wheel center section to check this.
Also, unless you have actually electrically tested the horn relay, I would check for a relay with the same part number (should be stamped into the case) and temporarily swap them. Your security system may employ a separate relay to sound the horn when locking or unlocking.

horn doesnt work


Lift the hood of the truck. Locate the fuse box and lift the cover. Check the horn fuse listed on the cover of the fuse box. If the fuse is blown replace it. Have someone press the horn and listen for a faint click from the relay or swap the relay with another one with the same part number (IGN or AC) to test the relay. If you hear a faint click the horn switch on the steering wheel is good. If the horn works after swapping it with another, the relay is bad and you should order a new one. Remove the horn connector and check the voltage with a 12 volt lamp connected to the two wires or a volt meter when someone presses the horn switch. You can also directly wire the horn to the battery to see if it sounds. If it does not sound the horn is defective. If you do not have voltage check the black ground wire on the horn connector to see if it has zero ohms, or if you connect the 12 volt lamp from the black horn wire to the +12 of the battery the lamp should light. If not your ground wire is bad. I hope this helps you find your problem, but if you have any questions post a comment and I will answer your question.

M3 convertible horn


you will need some help , but unplug the horn and then depress the horn inside the car and you will be hable to hear a clicking noise, either inside the car or in the engine comparment, have some one locate the noise while you keep depresing the horn on and of to get it ti click on/off
and other thing there is many cars with only one horn make sure to try contacting the dealer and ask for service department and ask for it, you should be hable to do it by phone using yellow pages, or getting the phone number at by calling 411

also when you locate the clicking noise thats the horn relay
i will apreciate the feedback thank you
