Fire behind dash from horn fuse

Most of the time it is not a fuse, it is the relay. Horns use alot of voltage to work , and therefore use a relay to close the circuit to make the horn blow. some relays are under the dash, some behind gloveboxes and a few in the engine compartment. You give no make or model of your vehicle so I have no Idea where it would be. You will need and electrical schematic of your make and model to locate the relay.

The fuse for the horn can not make it blow.only a bad horn switch/button can do that.The tail light fuse should be marked in the fuse panel.If you have the vehicle manual you can most likely find it in there.

Is got a short test the leads and see if they getting fire and from where? you dont have an alarm on this car just acting up ha? if is getting fire than is the horn switch getting stack

The horn should be behind the grille or on one of the fenders in the engine compartment. If you unplug it and the fuse does not blow I would say the horn is done.

that sounds like there maybe damaged wires or that there is a wiring fault. the new fuse you put in wasn't a bigger fuse then it is meant to have in it is it? cause if so instead of the fuse blowing the wires may melt together and damage parts or catch on fire etc.

The fuse block is located below the dash and mounted to the fire wall. This area is where the brake pedel is located. If you still can't locate the fuse, open the hood and the horn is located behind the grill. Remove the wire from the horn. To fix the problem correctly it's possible that the horn relay is stuck closed which is why the horn blows. A wiring diagram will show the location of the relay. Most relays snap into the holder.

There is One under hood and one under dash.Check owners manual under fuses.If fuse is ok it could be horn relay or horn itself bad.If you disconect horn and put a test lamp on horn wire,have someone blow the horn if test lamp. lights up ,horn is bad

all you need to do is run a wire(s) from the original horn to the new horn & if you blow a fuse put a bit bigger fuse in.....hope this helps ......cheers

Maybe horn became unplugged. Put 12 v power to horn make sure horn works. Put test light on terminal on horn have someone press the horn button, if light comes on and horn does not blow you may need new horn. if light does not come on you may have bad contact at horn button, blown fuse, broken wire, bad horn relay or possibly just a bad ground.

You probably popped a main fuse somewhere. Check all fuses under hood & dash. Try removing battery cables for a minute or so, in case of resetting breaker involved, just in case.
