Then you have a short in the wiring, the horn button is defective, or the horn itself is defective.
The horn fuse is the same as the stop lamp fuse
Dead short in the horn or the wire. Try unhooking the horn and see if it still blows the fuse. Stop pusjing the horn so much! :-) Actually there seems to be a short or a bad horn. Check for the horn relay as well it may be stuck or bad.
The fuse for the horn should be on the drivers side underneath the dash. There is a diagram on it that shows the horn fuse.
Check the fuse, and all connections to the horn. If you find nothing wrong, then apply 12 volts directly to the horn. If it blows the horn is good, and the horn switch may be bad. If it does not blow, visit your local salvage yard for a used horn. dont think the fuse in the fuse panel is the only one for the horn... in the relay center under the hood there is a horn fuse as well, that was where mine was blown. good luck
check the fuse
There is a dead short in the horn pad, take off horn pad and look for two wires touching or a hot wire rubbing on something that is grounded. First, disconnect horns in bumper area then press the horn button then check fuse. If the fuse is still good, hook up horns and press horn again. If it blows fuse it is the horn itself.
Bad horn? Bad relay? Bad horn switch?
No, it is not a problem with a fuse. May be a bad relay, or horn switch.
The horn and parking lights may be on the same fuse, you need to look for a frayed wire or connector leading to your horn(s), it may be touching metal somewhere causing a short. The horn itself may also be the problem to check it disconnect the wire connector from the horn(s) and try it, if the fuse still blows keep looking for a wire touching metal.
There must be a short in the system somewhere that causes the fuse to blow.
Depends on what is wrong with it. Start by checking the fuse. If it is good then apply 12 volts directly to the horn. If it blows you know it is good so there is a problem with the switch or wiring. If it does not blow it is bad and must be replaced.
Fuse? check your fuse box for the fuse indicated "horn" remove and replace if neccessary. if fuse is not the problem, check wiring to horn under the hood in the engine compartment.
