How do you fix the horn on a Ford Taurus or Mercury Sable?

the horn relay is in the center, behind the instrument panel, mounted on a brace

For 1996-1999 Taurus / Sable, the horn relay is on fuse #19 in the Power Distribution Box in the engine compartment

This is well detailed and illustrated in the Owners Manual - See "Related Questions" below for more

Not working?

If your horn is not working, it could be the wire connectors need cleaning. Find the horn in the very front corner underneath the passenger side headlight area. The connectors just push on - pull them off and clean the metal blade the connector attaches to.

Did that on my 1998 Sable 3 years ago and haven't had a problem since.

On my 98 Sable, it's up under the passenger side of the engine compartment - way towards the front.

Maybe the 2003 is still in the same neighborhood.

pop the hood on the car, and with the engine off have someone try to honk the horn. have them listen on the inside of the car and you listen on the outside of the car. if either one of you hears a clicking noise (anywhere other than the steering wheel) then you know that it is most likely your actual horn assembly under the hood, probably mounted by the radiator somewhere. if there is no clicking noise you either have a blown fuse, a bad relay, or a faulty wire connection.


The horns are on the way front - passenger side, just behind the bumper cover.

After confirming the fuse is good, check the wire connections to the horns. Mine were corroded and only one of the pair would work whenever it felt like it.

I pulled the connectors off and scraped at them with a screwdriver - enough to improve the contact and they have worked reliably since.

It is located in slot #30 it is a 15A. Look in the fuse box under the drivers side above the brake pedal.
