The Caravan horns are dual frequency horns. One is a higher frequency and the other lower. Try to determine which one you need by disconnecting the electrical connectors one at a time and get a replacement at a junk yard. Hella makes good replacements.
The horns being made and used today are not so very good. If you had access to one, you might try a used one, particularly if it were cheap. You would need to be certain that horn worked before trying it on the car.
A person with an volt-meter or a multi-meter could see if there is any electricity getting to the horn when you push the horn button. That would tell you if it were the horn, or something else.
You should also check the ground wire from the horn to the body, as the electrical components are no longer grounded to the frame, they now have a ground wire.
Many cars of today have the horn button and the air bag in the steering wheel together, so some shops will tell you it will cost up to many hundreds of dollars to fix the horn because the air bag is part of the horn system.
God bless your efforts.

The most common problem with this is the clockspring, it is located just under the steering wheel. It will cause the horn not to work, airbag light to come on, and the cruise not to work. There is probably a recall on this. Contact a local dealer to see if the recall applies to your car.

I had the same problem and yes, it was covered by the recall warranty - clockspring, which my dealer replaced for nothing. The warranty recall is lifetime, so it doesn't matter how old the vehicle is or if you are the original owner.

Simply have it replaced, horns on domestics usally stop working as mine did on my 93 lumina, it stopped working and I had it replace and it worked fine after that.
SOURCE: horn stopped working, fuse and relay is good
With test light check voltage at horn assembly on both wire's, could only have one, horn assembly itself could be ground, have some one press horn button while checking, if there is voltage replace horn assembly, if no voltage horn pad at streeing wheel bad. that's being fuse and replay are good.
