    Hi All, I know there has been a lot of discussions about horn problems , I have read them all but still confused. I have a late 74 Kombi. The horn never worked because the previous owner connected a air horn, now gone. The original horn is still there under the passenger side and does work. one wire connected to fuse box and another to ground. So what is the problem ? Well why is it that the ground wire where ever I touch metal the horn goes on ? I wouldn`t expect that.... correct me if I am wrong. I haven`t gone as far as the actual horn button on the steering wheel. Does this make sense ask questions please
    Regards Klaus

    Sounds like you may have hit the nail on the head?
    From your description my guess is a short circuit in the horn button or the wire to/from the button and the PO disconnected the horn to stop it sounding.
    Do you have a volt meter or 12 volt test light?

    The horn has power all of the time that the ignition is on and earths through the contacts under the steering wheel, using a test light or voltmeter with the ign on both of the terminals should have power, pull the brown wire off and earth that terminal of the horn and it should blow. If this is the case you need to follow the circuit back to the horn button, the wire is most likely broken at the bottom of the steering shaft.

    The horn activates via the earth wire (vs providing 12v to it via a switch). I got the horn on my 74 to work for a year or so after reconnecting it but it started activating when turning the steering wheel, at this stage I think the steering tube is making contact with the steering sleeve or it is shorting with the ignition lock making contact and causing it to earth.

    Unfortunately I can't remove the ignition socket (I gave up trying) and the horn is back on the dash via a push button.

    Can you put up a pic of your steering column. There is a difference in the 74 year where they changed the column and the 2 versions are quite different in wiring.

    The bottom cover on the later type column has no plastic ring and underneath it there is no spade connector. This one has a link cable that goes around the rubber coupling. If you have a late 74 it is what you should have. The earlier one is much more of a pain to fix.

    Here is a link that has pics of the 2 systems

    Have a look at that and see if that helps.

    Hello lovely Kombi Club peeps.

    It's Jane here, Dot's caretaker.
    It's been a while!

    Dot's toot isn't tooting. Auto Electrician says it is broken (?!) wants to put a thing on the dash, but I am trying to keep her 'traditional'. Apparently the parts are too hard to get? I just had a search on the Bus Stop but nothing that I can see. Thoughts?

    And Dot is a 1974 as well...

    Schmetts horn was working intermittently. Pulled the steering wheel and the brass tab that contacts the horn button had worn thru.
    Cut a piece of brass shim to match the tab and soldered over worn area. Back in tootsville.
    Also have a claxton type horn with a dash mounted button as a back-up!

    As horn is not working, I can only assume auto elect checked fuse.

    I would be checking the brass tabs as Apal has mentioned. That is the easy fix.
    If it’s the wiring that can be more difficult.

    You may need a kombi specialist rather than a stock auto electrician

    Check the gap between the steering wheel shroud and the steering wheel column.
    If it’s more than a couple of mm the horn will not work.
    Parts are readily available from JK.
    call them and ask to speak with Kai…….he will sort you out .
    Cheers,
    Mark

    Hey Jane,

    Most of the above will be near impossible to do with a broken wrist! :eek:

    As Barry said, I’d get a second opinion from a mechanic that knows Bays, and evaluate which parts need either repairing, or replacing, then contact Kai at just Kampers.

    Keep us informed, so we can help further, if necessary. ;)

    And Grant, as usual, so helpful, thanks. I will have a look at Just Kampers too. I'm in the market for some rear seat belts and a new Indicator handle.Oh and a new awning/tent as we drove off and left ours near Oberon! Pre flight checks now recommended...

    Oh yeah…..that was pre floods, pre covid, pre fires. That was a while ago. :)

    Guessing it hasn’t happened since? Or you have found a new, more reliable “help line”…… :D

    Barry - NO as they are for the T3/T4.

    It is called Indicator Cancellation Ring with VW Part Number 113 415 660A - just so happens the Horn Ring is integrated into it so you would need this https://www.mickmotors.com.au/produ...2-ty3-71-plastic-with-canceling-tab-7988.aspx. or https://www.justkampers.com.au/113415660a-indicator-cancel-ring-vw-beetle-1970-on.html. VVDS may have in stock as these 2 suppliers are Out of Stock or https://www.heritagepartscentre.com...r-cancelling-ring-including-horn-pick-up.html

    The one from Micks I put on the Type3 wood rim wheel - if it has 2 connection tabs for the horn then you'll have to note which tab to connect otherwise the horn will sound when you turn the wheel.
