Found myself a gremlin today. Horn's dead.

Fuses - check
Wiring connected to horn button - check.

I'm assuming the next step is to pull the wheel and look at the contact pin as that seems a common point of failure?
Also checking the wiring/grounds etc?


Other ideas?

As an interim fix other drivers need to keep an eye out for my finger! :D
 
Before pulling the wheel I would put 12V to the horns and see if they work. I do not think the carbon contact is a common failure but it does wear down...Mine was replaced only once. easy job but the part is held with rivets...so they do not expect it to be replace often.

Good plan. I'll do that and report back..
 
Swap relays
try horn

jumper pin 87 on relay base to pin 30
listen for horn

voltmeter on pin 30
12 volts?
 
Tackled this today.
Relays and wires all good after testing. Issue seemed to be a mix of dirty terminals, horn pin on steering column was cracked and one horn appears to be dead. After a lot of cleaning/repairing I've now one working horn and voltage to the second one (RH side) - I'll need to replace the broken one. Hopefully that's the end of it. @tferrer will be happy to know there actually were some black feathers behind the radiator :)
 
Put on that old bumper sticker: "Horn Broke, Watch for Middle Finger!"

(IIRC it omitted the word "middle" but I included it for clarity to our ESL audience)
 
Speaking of feathers, where I live a single tone horn can get you tarred and feathered.

In this perilous time until you fix the second horn I would practice making the second tone vocally, windows lowered of course.

Practice the A sharp or the F sharp depending on which one failed.

I knew it... Classic Black Raven horn curse.

I've been using hand signals to compliment the horn :)
 
Once we fix your horn I see help with a hard problem that has stomped all shops I tried. My VW Cabrio horn makes a very short beep when I brake hard... I think it started when the door lock cylinder was replaced.
