Hi there.
You dont have to put the horn in the same place as the other one so as long as you find out which 2 wires go down to it and fit the new horn to any where under the bonnet as low as possible and run the 2 wires from the old one to it and away you go

Visit the on-line store, know as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem.

remove right side headlight assembly and you will see the horn set

the horn is situated behind the inner wheel arch at the front of the car on the passenger side wing

Hi there,
ususally in Sonatas the horn fuse is situated in the fuse box located under the bonnet.
Cheers

You don't mention the year, but the location is probably forward of the left front wheel behind the bumper cover. Note that when working anywhere near the air bag impact sensors, steering column, or instrument panel it is recommended that you disable the system by disconnecting the neg. battery cable and wait 2 minutes before working on the car, to avoid accidental deployment of the air bag. Before all this though, have you checked under the hood (I mean bonnet!), fuse #6 in the power distribution center, and under the dash at the fuse block, fuse #7? If the horn isn't working check these 1st. Hope you fix the bloody thing! Let me know how it goes and if you need further help.
