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
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.
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.
I believe it is in the left front (driver's side) fender, I had to pull the wheel and remove the wheel well cover to get to mine. (2000 Taurus sedan). Taken directly from the service manual: The horn consists of one high-pitched and one low-pitched horn mounted behind the LH side of the front bumper fascia.

Another assessment... Many Ford products from around this timeframe shared a certain door ajar sensor, and they do "fail", or generate false open signals. This failure is easy to correct with healthy doses of a spray lubricant like WD40. NOTE: the target to spray into is the bottom side of the opening for the door latch. The sensor mounts just below it. By the way, if your Taurus/Sable has been sounding off the horn alarm…
These are easy. They should be located in the front engine compartment by the radiator or by the wheel wells. They are black and look like a horn and usually have one or two bolts attaching it. There is a wire you have to unplug from the horn. This is a hot wire so protect it from touching the metal surfaces of the car or grounding the connector. Most cars have one or two. But…
