replace it.
In a 1997 Mercury Mountaineer : In the Power Distribution Box ( which is " live " ) located in the drivers side of the engine compartment ( relay # 2 is the horn relay )
The mountaineer has a fuse box under the drivers side dash ,and it has two horn fuses , right horn fuse ,and left horn fuse.
I BELIEVE the horn is mounted below the battery tray
According to the 2006 Mercury Mountaineer owners manual : ( # 14 is a 20 amp fuse for the horn ) * in the fuse panel below the instrument panel on the drivers side *
In a 2001 Mercury Mountaineer : In the Power Distribution Box ( which is " live " ) located in the engine compartment , on the drivers side of the engine compartment : ( mini fuse # 10 is a blue color 15 amp fuse for the horn relay and the horn relay is relay # 7 )
I believe it is mounted below the battery tray in the engine compartment
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.
IT 'S ON THE RADIATOR SUPPORT BEHIND THE HEADLIGHT. THERE IS A HORN ON EACH SIDE.
Under the battery tray. A little difficult to get to bu tnot too bad.
The fuse for the horn is under the driver side dash right next to the brake pedal.
positive wire to another positive wire
Horn's should be in the fender wells in the engine compartment.
