I.C.E & Electrical / Re: Intermittent Horn Issue
So in the end I took it to a local garage, they fitted a new horn and they have run a wire to the live terminal on the battery, presumably by-passing the problematic live feed. The horn works well now and got through its annual inspection which was the end goal.

Just replace the horn itself.

Given that when i connected the horn directly to the he battery does this not rule out a faulty horn?

Yeah I realised that after answering which is why I thought about the earth as I presume you removed the horn from the car and brought it to the battery?

Yeah did that exactly, removed it entirely and put temporary wire to horn and it worked.

A few years ago I had some starting issues, local garage I think fitted a hot start relay. I am wondering if this might be what is required here too...

Disconnected the horn and checked with a multi meter and I have voltage as the horn is pressed. I then connected the horn directly to the battery and it worked so I am really confused now.

.. Also popped the button off the steering wheel, the contact and look clean and no corrosion, when I make the black and brown directly I get the same weak parpaing sound.

Checked the fuse for the horn which is fine and confirmed that this golf doesn't have a relay for the horn.

Starting to wonder if the horn itself isn't faulty.

Tried the car today, after a run in very warm heat the horn stopped working as befirr, it then worked once then again the problem returned. When it wasn't working it wasn't totally dead but sounded very weak, as if the battery was dead, which is isn't. Only noticed this once engine was not running.

Not sure if that helps identify the issue?

it is the original steering wheel - I did hear the contacts can get dirty and may need cleaning. Does the square button that is pressed pull off with the aid of a screw driver?

I.C.E & Electrical / Intermittent Horn Issue
The horn on my '90 Golf is intermittent, in most cases it will work fine. When I take it to the test centre and it has been driven for say 30 minutes, if I then leave the car running idle it will typically fail. I've tried turning the wheel and then pressing the horn but to no avail. Typically I'll then drive 5 minutes up the road and it will work again fine.

Any suggestions?

I.C.E & Electrical / Horn Intermittent
Hi all - I have a 1990 Golf CL (.?) Automatic which runs great, but there is an intermittent problem with the horn or klaxon. I can be idle after a good run and the horn just won't work, then if I pull away on the move and it works perfectly.

I suspect it might be the relay, I had a similar starting problem which was remidied by changing the relay. However checking my relays against the schematic I can't work out if I have a relay in position 11 or not. I have attached a photo, there is an L shaped copper piece in the socket which I am unsure about. It is position 11,to the right of the relay with the white wire.



Any ideas? Thanks in advance.
