Horn fuse keeps blowing out

the fuse blows because somewhere after the fuse , the wire is dead shorting out to ground
check / replace any horn relays

use a multimeter set on ohms resistance and that will tell you that it is shorting out as it will register as a circuit

new horn or relay gone most likely but make sure it is grounded good or wont work either hook battery booster cable from negative battery terminal to horn bracket if it works then clean mounting area under horn ground is bad

horn relay located on the right side kick panel,you will see a row of relays,if horn relay is okay, more likely your horn control pad has a short inside causing horn button contacts to stick causing horn to keep blowing.

check for blowed fuse or bad relay, you can hook test light to see if horn getting power when you press horn pad if fuse and relay okay,remove horn and hot wire it if it blows, more likely horn pad with airbag in steering wheel bad,if horn pad bad you have to replace whole airbag with with horn pad as a unit.if horn dont blow when hot wired then horn it self is bad.

disconnect the horn or horns, operate the horn and see if the fuse still blows. if the fuse still blows then there is most likely a short in the wiring. relays rarely cause shorts. if the fuse doesnt blow with the horn disconnected, reconnect the horn and operate the horn again, if the fuse blows you have a shorted horn.

horn may be shorted internally. Try pulling the connector off the horn, put in a fresh fuse, see if it blows.

If it still blows, you have a short in the wiring or the relay. If there is no obvious short in the wiring, change the relay.

If the fuse doesn't blow with the horn disconnected, replace the horn.

could be you might check it out. many items take the same relay so you might try exchanging it with another one with the same numbers. If that isn't it you may have a short in the horn itself.

Most common problem is the ground that the horn connects to wit the bolt is rusted and causes it to pull to much amperage so clean the contact first then if it still blows the fuse then the horn relay or the horn may be going bad.over time the horn gets junk in it and causes the coil to overheat and causes it to burn out. Horns cost $15.00 for a new horn and are easy to change. I doubt the relay is bad but it is always possible.

Well, it could be a fuse. Check the associated fuse, if it is ok then proceed to checking for power at the horn (it should have 12v). If the horn has power then replace the horn. If it does not then seek proffesional certified help due to the fact that the problem is going to be in the steering column or horn pad, and that will require dealing with the airbag system (which is NOT recommended) unless qualified.

there should be a relay box under the hood you will see the horn relay pull this out
