Re: horn wont work

Its a pretty common problem i've found. Know of atleast 5 cases.
Something went wrong in my horn pad with the 2 metal plates that touch to activate the horn. I cut up a computer mouse pad & put the pieces inbetween the plates.
Have you checked the connctions to the horn itself?

Re: horn wont work

Using a multimeter/12V light will help you diagnose the problem - to see if it's getting any electrons!

Don't bypass the relay like I did once!..........the dash/horn wire loom in the steering column won't hack the current.......sniff, sniff (from under the bonnet) - my dash was cooking. I duct taped the horn switch on so I could trouble shoot - bad idea!

Problem - horn buggered.

Cheers

Re: horn wont work

Hi, heres a few things you can try to diag it without tools or any major dissasembley. Since you replaced the relay already, first go to where its very quiet with no noise around, press on the horn and listen for the relay to click.
If you hear a click, that means the fuse and most likely both power inputs are ok at the relay. the hornpad is momentairly grounding the relay trigger and completing the main circuit to the horns assuming the relay, and the wiring to the horn from the relay is ok. The horns are the only thing that could be at fault, except if the horns themselfs were poorly grounded.
If the relay does not click when the horn is pressed, then first check the fuse, if the fuse is good and assuming the wiring is good, power should still be at the relay terminals, since the relay was just replaced and assumed good, the problem could then be the relay trigger ground, which is the hornpad contacts.
if the wiring going up to the steering wheel from the relay is ok, then the steering wheel brushes or sliprings might be worn or sticky, if at that time you can just take the hornpad off, take the wire and ground it to metal (like the steering shaft nut), if the horn sounds then then its the pad contacts themself.
If the horn doesnt go off then the problem could be in the slipring contacts, with the hornpad pressed down while pressure is forced down at different parts of the steering wheel it might be possible to make the wheel contact the worn or sticky brushes, so if the horn then sounds while your doing that, its in the sliprings that the ground circuit for the relay is open.
So in general, if a click is heard from the relay while the horn is pressed, then test the horns manually just to make sure, because everything else is ok.
if the click is not heard, the problem for the relay ground trigger up in the steering wheel is not working properly.
When manually testing the horns, instead of disconnecting them and testing them on a battery, leave them the way they are and first connect a jumper wire(preferred) or jumper cables carefully first from the + of the battery to the + terminals of the horns, if they sound, there good, if they dont sound connect a ground wire from the - of the battery to the horn body or ground it uses, this will check the horn ground itself, just incase it is the whole problem. if the horns then sound the horn ground should be corrected, if they still dont sound the horn, or horns need replacement.
Another tip is if you have dual horns, the horns are hooked up in parallel, so one can and usually will still work if the other one fails, if they sound more quiet or sick, then one horn is at fault and everything else is ok.

Re: horn wont work

the time ive spent working in New ford parts tells me its 99% definite on the horn pad.. sold hundreds of horn pads, TRAV351 is right on.. pull the horn pad off and short the wire out and you see the horn still works.. the metal contacts inside fail.. it is fixible.
