Where is the horn located on a ford f350

This is no BCM problem this is an steering wheel airbag problem the cover is warped and this causes the horn to honk like you are pressing it.

Horn fuse is located under the dash in location #12, it's a 15A fuse. The horn relay is in relay location #3, also under the dash.

most likely the clock spring needs to be replaced which is located in the steering column.

time to replace the horn,when it goes quiet its the diaphragm that gone........

It is most likely a part called a clockspring. It is located behind the steering wheel. When that part is defective you will almost definitely lose your horn, airbag, and cruise control. If it is not that it is probably corroded at the harness located on the steering column or at the cruise control module in the engine bay. If you have tilt, which you probably do, those wires can become frayed at the plug or directly after the plug at the column. I would start with fuses, then wires, then clockspring.

there is a short in the horn wiring, you may disconnect the horn relay, that the easiet thing to do. owners manual should have a layout of where the relay is. Steering wheel switches most likely.

The horn is located on left side of radiator below head light. You will have to remove left (driver side) battery and tray to gain access.

check fuse and also check the wire going to the horn and check the inside of the horn too and check the ground
