1. The Fuse is in the Power Distribution box ( under the hood ) , fuse # 7, 20A
2. The Horn Relay is in the Power Distribution box, Relay # 205.

3. If you need an owners manual, download one here :

4. Obviously check the fuse and relay, but if both check good, don't be shocked. Could be the clock spring causing the problem, but do follow correct problem diagnoses first by checking the fuse and bench testing the relay.

One other check, while you have the relay out bench testing it, is to bypass the normally open contacts together. The horn relay should be a Ford half size ISO relay :


Double check this, but if you short those pins together, the horn should sound ( if the fuse is good that is ).

You can also use this diagram to help with bench testing the relay. Ground is what is switched to it, power is constant.
