My coach has a switch on the dash to switch between the air and city horns, so I'm going to assume your setup is similar and the city horns are working. Check the 12v solenoid located in the compartments above the dash to make sure that air is getting to your horns. If air is getting to your horns and they're still not working, you will have to remove the back cover plate on your horn and check to see what the problem is. Once you have the diaphragm removed you can check to see if wasps built a nest in the trumpet. Mine were not working when I bought the coach but taking them apart and cleaning the diaphragms and removing obstructions in the trumpets fixed them right up. If you need parts Google 'Hadley air horn parts' and you will find numerous vendors that sell them.
