You can work on this safely after you remove the positive battey terminal and wait 5 minutes before working on the horn system. you remove the air bag first there are two security bolts that hold it on you will have to buy these at a parts store. Auto zone sells the Set of Lock out bolt wrenches for removing the bolt. you will also need a steering wheel puller to get to the ignition key cylinder holder that is where the contacts are located. But first I would remove the horn ground out the horn and apply power to the horn to see if it works. Normally it's the horn relay that goes bad.

the older cars like that have little contacts that touch each other and if they touch the hor blows. the cover needs to be taken off and readjust the contacts. its alot more difficult when there are airbags. so DO NOT attempt if there are airbags in the car. very dangerous

well there is a clock spring in the stearing wheel for the horn and one for the airbag. and the one for the horn might have broke. i have been told that it cost over a grand to fix. so this is why i still drive with out a horn lol

SOURCE: horn button sticks
Typical scenario of the horn pad needing to be replaced at the steering wheel, may have to search the wrecking yards for a replacement or take the pad off and try to discover what part of it is bad and try to repair what you have.
Some folks have added a button useing the same twop wires that control the horn pad, thus eliminating the need to find a replacement horn pad in the proper color etc. a hole drilled into the dash and the button installed makes it a lot easier and cheaper and yiou still have a horn.
Every once in a while the horn relay is the culprit but mostly it is the horn pad, be careful of the air bag deploying...disconnect the air bag fuse before doing any work on the electrical inside the car.
