Silly question I know. but where is the horn hidden.

Hi,

My Horn died a week or so ago and is due for its NOT. Sods law. It initially made a clicking noise so probably the relay switch (or so I gather from other posts). I have checked the fuse and swithched the relay swithches around with no luck. I don't know how easy it is to check or change the wiring. It is a tight fit to look under the steering wheel. I cannot see where the horn is hidden to try and check it out and see if a loose wire is involved. Also where do the wires go from the horn buttons. I presume down by the wheel. Do I need to remove lots of stuff to get at it. Does anyone have any pics of it pathway. Not a wiring diagram as that is like Algebra to me. Just good old fashioned photos.

If not when if I fit a new horn what are the laws on it. Can it be activated by a switch. Does it need to go to the original buttons. Does it have to go beep or the equivalent or can I use one of the cheap PA systems on Ebay that do rooster noises, etc.

Thanks in advance for the help.

Sorry for posting it here, but my searches did not fid a post saying where the horn is. MAybe it is that obvious, but for the love of me I cannot see it.

Hi Asda B,
Try looking behind the front bumper, (left hand side as you look at it.) number plate height??
To the side of the rads? I got two of em down there..!

Thanks for that,

I have found a horn. It was tucked up out of sightabove the bumper height.I can only see on and the wire looks fine. Now it is dark it ssems easier to sse as I need a torch, but boy was it tucked awy.

To test it do I presume one end is earth so I just need to find a wire to run from the +ve terminal of the battery to it. Or do I need to complete the circuit with a negative. I presume the one wire I see is going to the positive terminal so I don't need to search out a +ve terminal.

Don't ask me why, mine just came with two.. ( A two tone parp!)

You got me with the horn wiring question...!!

Logic would tell me (say if i was to wire one up?) To have the horn running off a relay, switched & triggered to sound when the relay goes to ground, say with the button push on the wheel grounded through the steering column..?

But i could be wrong!

Geoff (g8dhe) is the guy who would know fer sure..

He seems to pick up on things if i put his name in a post!

But i'm carful not to wear it out...

You must have a trendy Bongy, Mine is just ASDA Basic.

The Horn itself is earthed thru its own fixings to the chassis.
The wire you see coming from the Horn goes to a relay, which connects it to +12 volts.
The relay is operated by the switch on the steering wheel, which puts an earth out to the relay to make it operate.
The relay is positioned down by the battery and is marked on the diagram below as F3-03 its position varies depending on Diesel or Petrol;

You can often here the relay click, or if you put your hand on the cover you should feel the vibration, when someone else operates the horn switch. If you can hear or feel it clicking then the chances are its the horn that's corroded, if you can't hear or feel it then it could be the fuse (top row 5th from left) or the switch or wiring that the problem.

P.S. You beat me to it Jaylee

Thank you for the expert advice. Hopefully I will be able to sort things out.

How do I get to the horn to change it. Do I have to remove the headlight? Or is that going to be difficult. To check it is the horn can I just wire up a lead from the +ve terminal of the battery and touch the lead on the horn as the chassis should presumeably be earth. Or do I need to run a second wire to the horn from the negative terminal (and if so what size/type of wire do I need to buy to cope with the current or will the horn just die with the battery wired across it). Or is that dangerous due to the currents and I should do it via a fuse in the car and if so How do I do it. Electricity at school seemed so easy, but I suppose the batteries were far safer to play with and the teacher told us what to do.

I hope someone can help

Yup, whip out the driver's side headlight, it's just underneath.

Using a test lead to feed 12v direct to the horn input terminal, with it still bolted in place to provide the earth will test it for you.

As long as you are not using ridiculous thin wire, a quick tap will test the horn without blowing or melting anything. 16/0.2 is OK for 6A, should be fine - just make sure you don't short it out direct to ground.

I have managed to get the grill and drivers side lights off and find the Horn. (well impressed with my self) Then I connected a wire from the horn to the +ve terminal and it worked. Yippeeee!!!. The horn works, but WHY DOES IT NOT WORK!!! I cannot open the bonnet and take the grill and lights off everytime I want to use the horn.

I have replaced fuse number 5 with several other 10amp fuses from the bongo and the horn never worked. I have also moved all the relays into every possible order in both the front and the back box behind the headlights and the horn never worked.

Surely if more than one relay was broken then I would have other problems with the car.

What do I do next?

Do I have to take the steering wheel and column apart to find a fault. Can anyone guide me on what to do and if possible direct me to some images.

Thanks in advance.

I managed to make mine stop working when I was installing something (can't remember what I was up to!) - There is a white plug/socket connector under the steering column which you get to by removing the wee panel on the bottom - 2 screws - I'd disconnected it for access to something else and forgotten to reconnect it.

Quite possibly

But first I would try to see if you can make the relay operate by connecting an Earth to the relay coil on the F3-03 Connector;

on the wire coloured Green with Orange stripe, if that makes the relay operate and the Horn sound then it has to be connection back to the Horn switch or the Earth on the switch itself, there is another connector E1-01 where the other end of the Green/Orange wire terminates not quite sure where that is but I would expect towards the bottom of the steering column, again Earth the Green/Orange and see if it works, if it does then its up to the switch itself which has another plug close to the Airbag (if you have them) as I recall. There were some photo's on the forum, I'll try to find them.

Ah yes, Kirsty did some work last August its seems, try this thread, its quite long, but a lot of photo's included.

That will be my next mission. I will try on Saturday. Lets hope it does not rain too much. I need to get it done before its MOT runs out on Wednesday. Being colour blind might make it inteeresting, but the Mrs will help with that bit. I am almos hoping I need to attack the steering wheel now there are some pics for me to look at. Thanks for the help.

I took the brave step and decided to take the steering wheel off. After a long seach it recommended in places to disconnect the battery. A good idea so the Air Bag doesn't go off in my face. I took the rubber bungs off, but for the life of me could not get the 4 bolts from the underside of the wheel to shift. Is there a special trick? Do they turn the oppsite way. I don't suppose I can just pull the front cover of the wheel off where the air bag sits under and the horn buttons go through. Just asking incase you can, but I am sure the answer is no.

Can I get to the wires from the relay. If I unclip it on the left hand side it moves on that side but not on the right. If I pull it up with force will it break something or is that how I get to the wires?

I may have to got to an electrical motor mechanic to find the prioblem for me. Or will a mazda garage be able to cope with it. Any idea how much they will charge or should I go to a bongo garage?
