Horn doesn't work-cruise does

could be a problem with the air bag contacts. what you do is remove the bag, ground the horn wire and see if the horn works, if not, then you need to do more serious diagnostics, if it does work, then you'll probably need to replace the bag itself. (I have a t&c that the contacts failed in the bag.. so I just don't have a horn, I can deal with that.. so I installed a bumper sticker that says 'horn broke watch for finger')

I got the horn works with key fob activity so that rules out the horn and relay. did you swap the air bags before or after I suggested that could be the problem? So where is your problem? With a wiring schematic, it's nearly obvious that the problem lies between the relay and contacts in the bag. You've eliminated the bag so now it's time for you to use proper diagnostic proceedures. With a wiring schematic and a DVOM, it is easy to test out the circuit.
