    my friend drove it drunk and hit a speed bump to fast.the horn went off and wouldn't stop. he shut the truck off and said that it wouldn't stop so instead of pulling the fuse out he ripped the wire for the horn out from under the hood. i hooked it back up and the fuse blew. i replaced that and it worked twice and then stopped. the fuse is fine so i figured the relay was bad.

    Ok i pulled off the trim and i have no 4 wire connector by the steering wheel. i do have a 3 wire connector with green w/red tracer, green wire and a brown wire. is that the connector you are talkin about. also if i pull that out is it going to cause the airbag to go off? do i need to disconnect the battery? thank you!

  • jayblue23 Feb 19, 2009

    okay when i tested the connector the horn blew so that means that the clock spring is bad right?

    Clockspring Toyota part number: 84306-30120

    Expect to pay about $225.00 for it.

  • Toyota Ed May 11, 2010

    Yes, indeed. The clockspring is bad. To replace it, you need to pull the steering wheel off.

  • Toyota Ed May 11, 2010

    Yes; The green with the red trace goes to the body computer. If you apply a ground to that wire, the horn should blow. If not, you would need to test the horn for operation by itself. It he horn works disconnected from the vehicle, and does not work by grounding the Green with a red tracer, you may need a body computer. Expensive part. Do not disconnect the battery, the horn will not blow if you do, when you test it. Just AVOID any YELLOW wires when grounding the Green with the red trace wire. Let me know how the horn tests out.

  • Toyota Ed May 11, 2010

    There is no horn relay on your vehicle. The horn is controlled via the body Electronic Control Unit (commonly called the "body computer)...

    The green with a red tracer applies a ground from the horn pad assembly on the steering column, under the horn pad.

    What I would do is pull off the lower steering colums trim, and locate the green with a red tracer in a 4 wire connector close to the steering wheel. Unplug the connector. Apply a wire to the green with red tracer; see if the horn blows. If it does, my esteemed collegue Emissionwiz's diagnosis is very correct, you have a bad air bag spiral cable "clockspring".

    Try that and let us know.

Have a friend, (or in-law) someone you're not too fond of, stand in front of the truck while you honk the horn and have them pinpoint it for you.

A horn relay will be located under the hood in the fuse/relay block. Check in your owners manual under fuse/relay to see a diagram. If you have no manual go to BBB Industries online under technical bulletins and wiring diagrams to look up your exact year

Horn quit working. Fuse looked fine, still changed it and nothing.

there are 3 parts, the horn, the horn relay, and the horn switch. horn relay is simple to check by replacing it with another from a parts store. it is plugged into a fuse panel inside the car or under the hood, look at your owner's manual for exact location. the horn can be disconnected and then jumpered directly to the battery. an old extension cord with the ends of the wires bared makes a find jumper cable. horn is usually located next to and in front of the radiator. if the horn honks it is good, if not you can buy a generic one at a parts store. if it is not the horn nor the relay then you are looking at replacing the switch inside the steering wheel and this is generally beyond the scope of a non-mechanical person.

Horn malfunction

Under the hood of your jeep on the passenger side there is the Power Distrubution Center (PDC). Remove the lid and thered will be fuses and relays in there. I could not locate the exact location of the horn reley, but if you start removing them one by one you can find the horn relay. You will know the right one when the horn stops.
