Might be a fuse,or a bad ground.
Do you have a air bag light lit on the instrument cluster ? I ask this because , if the air bag light is lit , could be a clock spring problem . I know ,what the heck is this guy talking about . You have a air bag on the steering wheel ,the horn button is on the steering wheel . The clock spring is located under the steering wheel , in the top of the steering coulmn . It has flat wire tape in side that allows the steering wheel to be turned full left to full right , keeping the horn , air bag , an any other button's on the steering wheel connected electricly to the vehicle. Plus there is a relay , when you push the horn button it energizes the relay turning on the horns. Watch these videos , will explain a little better .

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 recently had the same issue, but my airbag warning lights also turned on. If this is the case, it might be the clockspring. There is a recall on clocksprings for Caravans 1998 - 2000 I believe. I got it replaced for free in the dealership. Enter your VIN in this site and it will tell you if you are covered in the free replacement warranty.

It's the " clock spring " . Dodge has a lifetime recall / replacement on this part. Somehow it controls the air bag and is tied into the horn and cruise control .

I have the same problem and it's not the rely or fuse... that would be too easy.
2000 Dodge Caravan ABS Light
Question:
2000 Dodge Caravan. The other day my light for my air bag came on,
but I noticed when it came on my cruise control stopped working and my
horn doesn't work when I push on it. However the horn does work when you
set off the alarm. Is it a fuse that's gone bad and if so which one is
it.
Thanks for all your help.Christy
Answer:
There is a device inside the steering wheel called a Clockspring.
Basically it looks like the main spring of a watch. It's purpose is to
insure perfect electrical contact with the airbag module in the steering
wheel. Wiring for the horn and cruise control also go through the
Clockspring. When the Clockspring goes bad you lose horn, cruise control
and the airbag light comes on.
On 10/5/2004 a Motor Vehicle Recall, number 04V480000 was issued on
this vehicle for this problem. From the recall bulletin:
Summary:
ON CERTAIN MINIVANS, THE DRIVER'S AIR BAG MAY BECOME DISABLED DUE
TO A FAILURE OF THE CLOCKSPRING, WHICH IS LOCATED IN THE HUB OF THE
STEERING WHEEL.
Consequence:
THIS CONDITION WILL MANIFEST ITSELF THROUGH ILLUMINATION OF THE
AIR BAG WARNING LAMP, AND COULD EVENTUALLY RESULT IN A DRIVER'S AIR BAG
OPEN CIRCUIT, IF THE PART IS NOT REPLACED IN A REASONABLE AMOUNT OF
TIME.
Remedy:
DEALERS WILL REPLACE THE CLOCKSPRING ASSEMBLY ON ALL COVERED
VEHICLES WITH 70,000 MILES OR LESS. FOR THOSE VEHICLES WITH MORE THAN
70,000 MILES, DAIMLERCHRYSLER WILL OFFER AN EXTENDED LIFETIME WARRANTY
UNDER WHICH IT WILL REPLACE THE CLOCKSPRING AT NO CHARGE IF IT FAILS.
DAIMLERCHRYSLER WILL ALSO REIMBURSE OWNERS WHO HAVE PAID TO HAVE THE
CLOCKSPRING REPLACED ON THEIR VEHICLES. THE RECALL BEGAN ON OCTOBER 12,
2004. OWNERS SHOULD CONTACT DAIMLERCHRYSLER AT 1-800-853-1403.
So at this point you should call your Dodge Dealer and make an
appointment to have the recall performed on your vehicle.
