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.

95 GMC Sierra horn does not work, fuse keeps blowing.


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

Fuse keeps blowing when I honk the horn. 2011 Mitsubishi Galant SE


Try disconnecting the horn and see if the fuse still blows when you press the horn button. If it does not blow the horn is probably bad. Buy a new horn.

Keep blowing horn fuse


that is easy, a shorted horn or its wires.
there are only these ways to find it.
1: pocket full off fuses, and pull horn lug and test for blowing fuse.
2: and ammeter,.used to find it.
3: visual inspection of the whole horn wiring harness.
they also sell a fuse adaptive circuit breaker (test) so you dont need a pocket full of fuses.
4: willynilly guessing, new horn, new horn relay, then dang back to #1 or 2.

For 2004 ford truck f150 extended cab, I found the horn fuse, where is the horn relay?


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.

2006 grand prix horn fuse keeps blowing. what should i look for


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.

2008 Ford Escape Horn fuse keeps blowing after replacing alternator. Horn sounds once then the fuse blows. Also radio and song info that displays in the dash console with the compass does not work... The...


I would trace the wire from the horn and see if it was inadvertently damaged when the alternator was installed. If you have a voltmeter, you can remove the horn fuse and check to see if there is continuity between the horn (non hot side) of the fuse and the car body. This would indicate a short in the wire running from the fuse box to the horn. You can also look around the alternator mounting area to see if any wires are being pinched. Hope this helps. Good luck!

Horn fuse keeps blowing out


Check the wiring around the horn and make sure nothing is touching metal...look under the hood at the horn and make sure everything is pluged in and there is no water on any plugs or wiring...Make sure the fuse is the correct number (ex: 10, 20, 25) If it is still blowing out the fuse then you after you do some checking then it is a short in some wires

Horn keeps blowing steadily without touching horn button area


The horn pad is most likely sun warped, ther is no other reason I know of, and yes it will be very expensive if you have an airbag.
