The fuse panel with the horn fuse and relay should be adjacent to the battery.
Under passenger headlight. Pretty close to the wheel well.
2 different fuses
It's fairly simple to find out if your horn fuses need replacing on our 2001 Mercury Mountaineer. If the fuse is blown, the horn will no longer sound.
On the LW200 it is in front of then right front tire, just behind the bumper. It is small, about the size of your hand.
As far as I know, the horn is behind the driver's side headlight.
its in the engine compartment fuse box, unscrew the top, and on the inside of the fuse box is a diagram of which fuses are where. my horn fuse is in the top left.

Have you checked your fuses?
It could be the horn relay which is typically located in the fuse box. It could also possibly be a defective horn switch which can be checked at the proper relay pin location. You will need a service manual for the proper pin location. The wiring could be bad. Or it could just be the horn itself.
The most likely common cause is a failed clockspring in the steering column.
It is important to know the layout of an owned car. The fuses and horn relay are located in the fuse box, that is under the hood.
Open the front passenger door and the fuse panel is in the side of the passenger seat.
