Which side is not working on the air horn?? If you remove the ceiling on the right side cabinet, you will see the air line for the passenger's side. If not secured properly with clips it will kink and the air horn will stop working. Same on driver's side. You may have a bad diaphram. Under the dash there is an air solenid with a tee, it may be under the coach itself. Crack each supply line and make sure you have air going to eash horn. Or, start at the top with the horn not working. Remove it, and remove the supply line and see if you have air. That should be a Hadley horn
The flush nozzle should be behind the trim that covers the black and gray water handles. Remove the panel and look up and you should see the nozzle. Remove the nozzle and clean with Simple Green, enlarge the holes one drill index size, replace with silicone and stainless steel screws. If the nozzle is not there, it is a different animal and you need a different approach. E-mail me direct and I will help with the fix if the nozzle is not there.
Been there, done that, with both problems, twice.
