check to see if there was a recall. I have a 1996 Plymouth grand voyager and the garage replaced mine free of charge.
The problem is most likely the clockspring. Go to this link it will tell you what to do. http://www.automotive.com/1997/49/plymouth/voyager/recalls/38659.html
Checking the fuse is definitely a great idea. Is it just the horn or everything on the steering wheel? If it is everything, it has been my experience that when the horn or any of the options on the steering wheel do not work, it is most likely the clockspring. That is what was wrong with my vehicle. Luckily for my van, the clockspring is a dealership RECALL ITEM. Another indication that it could be the clockspring is the AIRBAG or possibly ABS lights staying on.
The clock spring is located behind steering wheel. If clock spring is defective, it has been recalled for your vehicle and has a life time warranty .
Not advisable, it could come back to haunt you. If it is because the air bag light is on 90% of the time it is because of a defective clockspring.
The clockspring is the electrical connection under the steering wheel. If it is broken the horn and cruise switches are no longer part of the circuit.

Start with the simple stuff. First check the fuse, and you can even pull the cover off of the horn relay in the power distribution center and manually activate the relay to see if the horn works. Most likely cause of this is a faulty clockspring. Usually with a faulty clockspring, the airbag light will be on, the cruise control will not work, and the horn will not work. This is very common on these vans.
