My ford KA horn has stopped working

http://www.bbbind.com/free_tsb.html

Hi Rougue, The link below shows a horn relay and a horn fuse which I marked with an arrow , I hope this helps..... CHEERS..

In the fuse box with all the other fuses under the dash or the hood ,check your hand book for location.

not sure but in most cases under the hood or on side panels on dash wich you cant see unless door is open.

Your horn will be located below the passenger side headlamp mounting bracket. It has a green/red wire running to it. If the wiring is good than check the horn relay (behind left side of the instrument panel) and also fuse labeled STOP (15 amp). If all of this is good than either the horn switch on steering wheel is bad or the horn itself is bad.

Did you check the fuse for the horn ? Engine compartment fuse panel, fuse #7, 20A

You can pull the horn relay, and jumper the normally open contacts to see if the fuse, horn and grounds for the horn are in working order ( this operates the horn without needing to use the horn button ).
The Horn relay is a half size Ford ISO relay in the engine compartment fuse panel ( check your owners manual to locate relay 206 ).

Diagram to jumper the horn relay, with this in place, the horn should sound as long as the jumper is in place


If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

As far as the horn, check for a blown fuse, if fuse is ok, locate the horn underneath the hood, check for power at the horn while someone else is pushing the horn. If you have battery voltage at the horn while someone else is pushing the horn, chances are you have a bad horn. Airbag light, check front impact sensors for damage or corrosion, unhook negative battery cable before touching the frontal impact sensors, Good luck, Gary

LOOK IN THE FUSE BOX UNDER THE DASH ON THE DRIVERS SIDE

Hazard warning lights and horn on a 2006 Ford KA don't work but indicators do

The horn is usually between the radiator and grill Assembly. The fuse is in fuse panel under the dash on the drivers side. Look at the lid and it shows the fuse placement and there use.
