    Great explanation. I only wish I had seen it before I changed out the clock spring. So after I changed the clock spring and found my horn still did not work, I found your video. 20 min of testing would have saved and 1 hr of work and a little cash. The horn relay was this issue. Swapped two relays to confirm. Thanks

    Prior to any disassembly try turning the wheel full left or right and check the horn. If it works on the hard turn and not when centered it’s your clock spring.

    Great helpful video. I put a new clock spool in and the airbag light is off. The 10A fuse is good. I'll check the horn relay tomorrow with my voltmeter while a friend is pushing the horn, following your video.
    The horn still doesn't work at this time. Is there a microswitch inside the airbag assembly that could have gone bad? I hit a deep hole up north and that's when it happened. I hope it's just the relay and not the whole air bag gone bad.

    • @737mechanic
      @737mechanic  2 місяці тому

      There is no microswitch just the horn button that makes contact when you press it and supplies the ground for the relay.

    I wired in a aux horn button … driving a pin in where you did at 19:40.
    Just hot glued the pin, zip tied the wire…
    Put it all together and pushing on my steering blows the horn now….

    @stevenzych2105 7 місяців тому

    Following your troubleshooting steps I have verified my horn is functional by connecting direct to power and ground but jumping terminals 3&5 of the relay do not sound the horn. But the correct 1 & 3 terminals have power and the fuse is good. Could the ECU actually be affecting the horn if the relay terminal jumper test isn’t working??

    • @737mechanic
      @737mechanic  7 місяців тому

      The ECU does not control the horn at all. If you have power on 3 but jumping 3 and 5 does not sound the horn then you have a bad connection or broken wire from terminal 5 to the horn. Terminal 5 runs directly to the horn so if you put power to terminal 5 the horn should sound.

    Great video! Electronics are not my strong suit - I'm much better at turning wrenches.
    Question-- 1 and 3 on the relay have power and 2 also has power when I press the horn button, but I can't seem to jump the horns to work. To me, that seems like the relay is potentially still good, but I suppose I can swap out for another and remove all doubt. Where do I go from here? Seems like my issue is on the 5 pin side of the relay. The wires on the horns do seem to be plugged in, but I wouldn't expect them both to go out at the same time. Potentially a bad connector somewhere?

    • @737mechanic
      @737mechanic  Рік тому

      Jumper pins 3 and 5 together and see if the horns work. If they do not then jumper 12v to the horn connector itself and see if the horns work. It sounds like you have everything you need at the relay, the question now is are the horns bad or do you have a broken wire. As far as both horns going out at once. That probably wouldn't happen but one could have been out for a long time and you may have never noticed because the other one worked until it went out.

    • @paulgilbreath4914
      @paulgilbreath4914 Рік тому +1

      Well, after looking at the horn wires, for some reason I was expecting to see + and - wires going to each horn. There was something funny with the first connection and removing and reinserting the connector seems to have fixed the issue. The wires into the connector seem to be nice and tight. Maybe it just wasn't seated properly even though it felt snug.
      What a great exercise in troubleshooting and I'm glad it was something simple. Thanks again for the video! Now on to the next project before winter - new cv axles.

    Why would the 10 amp fuse keep blowing? This occurs with the truck sitting off and not in use. I switch the fuse and the horn works. I'm not sure when it blows because everytime that I've noticed is after I've driven the truck, parked it, and returned later. Due to Covid, the truck was sitting unused for 3 days when this happens.

    • @737mechanic
      @737mechanic  4 роки тому

      Are you saying it actually blows when it is sitting? There shouldn't be any way for it to blow unless the horn button is pressed. Either way what I would do is unplug the horn/horns behind the grill and see if it still blows if it doesn't then the horns are causing it.
