The fuse looks OK. I hear a click from the steering wheel when I press down, is that the click associated with the relay? If not, how much should I expect to be charged by a shop to replace the relay? If it is the wiring behind the airbag, how much is that repair likely to cost?
more than likely it is the horn itself in the fender that got water in it and died. i have a 97 sunfire that had the same problem so i got a new horn for 12 dollars and hooked it up but instead of putting it back low in front of the passengers front wheel i tucked it behind the front bumper on the radiator support . it doesn't get wet and been perfect for two weeks now!!! hope it helps you!
Just cut off the old plug and crimp on new ends.
