Horn not working!

My horn has stopped working. I have checked the fuse but obviously that is fine as interior light is still ok.

Any ideas what I should check first?

( I know this is simple, I will check the steering colomn stalk then the horn itself but thought i'd ask so I am better informed when I look tonight)

i think its basicly wired power from fuse (purple) to switch to horn (purple/black)
i would just pull the wire off the horn put a multimeter across to see what power is coming through if you get 12v or so the a guess at bad earth or horn is faulty.
if low volts coming through and your getting power to your stalk then i guess the switch is to blame or could be the wire feeding the horn is worn through.
well somthin glike that anyway. i'm sure someone will correct me

what vehicle have you got?

If the fuse is ok, wouldn't it be quicker/easier to start at the horn n work back? U can check the horn is earthing properly too that way.

Is it a 1 or 2 wire horn? Some need an earth wire - some dont.

I have a P reg 90 truck cab.

I will start at the horn and work back then.

Thanks for replies.

Worked fine last week!

I have taken the horn off tonight. Its got black and purple wires. I used some sand paper and cleaned the connectors and reconnected it all but no joy.

I have not got a voltmeter so am scuppered!!

I wondered if there was something else I can try?

stick a 12volt lightbulb across the pur and blk wires - see if it lites up - if it duz its the horn - if it dont its wiring.

oh and follow the black back to see where it is attached to the body and clean it up.

Try VIAGRA - my horn works lovely now

just a long shot, you havent disconnected any aux lights or anything have ya?

take 2 pieces of black 1" pipework, tape them together. Wind the window down and each time you are tempted to use the horn poke these out and shout very very loud...far more effective.
