Besides the standard auto horns in the engine compartment. I also have what appear to be air horns on the roof (Maybe Electruc?). Can't find any compressor and they don't work with the horn button. No other horn button visible. Were these factory?

They rusted inside very quickly and are not repairable. They are marine horns, shop around for price. Rv places wanted $159.00 I got new ones through a marina for $59.00. Exact same as the factory on 2003 Pace Arrow
