When you press on the horn button do you hear the horn relay click? The start at the horn, bench test it, if it works then check for power, is the fuse good and is the relay ok. If the stuff checks out then it may be the horn contacts behind the steering wheel.

Hello:
I have a 1999 boxster as well with the same problem. The short term fix is much easier and safer than removing the fuse. I called and spoke to Doug at Champion Porsche in Broward FLA and his suggestions worked like a charm so I was able to drive my Porsche to the dealership.
Take a regular size business card and fold it 2-3 times, looking at the crest on your horn lift the back of the horn assembly ever so slightly, if the horn goes off you lifted it to much. Take the folded business card and wedge it behind the horn. Problem fixed for now. You can press on the horn to ensure that this patch is working and it should.
Cost was $236.00 parts and labor.

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.

One simple solution would be to act european and use your bright lights to let folks know you are miffed instead of the horn. j/k
I agree that it is something internal to the airbag module. Looking at the steering wheel you see a vertical line running down the center where you would press for the horn. Under the covering are thin pieces of plastic that have circuits in them. Most of it is within the plastic, but in a few places they bare. They are seperated by a very tiny gap. Then you push on the covering you close the gap against the hard plastic layer that actually covers the airbag. This closes the circuit and turns the horn on. Normally when you release pressure they seperate again and the horn stops / turns off. It sounds like somehow the thin sheets have become stuck together and the horn is now always on. I cannot think of a good way to fix the stuck problem short of replacing the airbag module.

wiggle the horn on the colum if it stops then the spring on the horn pad has gone bad

I had same problem. Could be the remotes need to be reprogrammed or replaced; or one of your door locks might not be working right.
