Your truck has 2 fuse centers, the horn fuse is located under the hood in the fuse/relay box on the drivers side just next to the brake booster/master cylinder. The Horn fuse is marked #10 in the box and is a 15 AMP blue fuse. This fuse supplies power to the horn relay which is marked #7 in the same box. If you do not hear this relay click and the fuse is ok then you have either a burned out horn or a defective rotating contact under the steering wheel that connects the horn button to the circuit, it is called the "Clock-spring" contact.

The horn fuse for this 2002 ford f150 is located in the engine compartment fuse/relay box , heres a diagram of that box , i circled the fuse for the horn, it is in location f1.7. hope this is helpful. also you may want to check the horn relay thats also located in the same box and i circled that also. have a good day.

Hi! You may want to start looking at the fuse box located underneath the dash on the driver's side. The fusebox cover usually has a legend that tells you the designated fuses and amperes. Replace the horn fuse if busted. Have a nice day

is it the fuse or the reley look at the salvage yard and find manule buy it for 5 bucks and locate the fuse if not fuse ask dealer for reley and location of reley

under the hood in the fuse box all the big square ones are the relays. activate the horn again then remove them one at time to locate the horn relay, when found rotate with known good one. If this doesnt locate the problem the then problem is in the steering wheel.

Under Hood on top left front tire wheel wheel there is a fuse box. Snap off the top and locate on panel, it should be a 15 amp fuse.
