non working air horns

[Golf_Guy]

Bought this used 05 Newmar 37' Kountry Star and the air horns are not working. When I turn the switch on the dash I would expect the horn would switch from honk to air horns when pushed in the center of the wheel. Nope same old standard horn honk.
I have checked the 50ampn fuse that also runs the onboard computer under the hood and it is fine. Could there be a solenoid that is out or something else to look at?

Thanks for your input.

Most likely the solenoid...I replaced mine this year when it was doing just that...you might rap on the solenoid with the handle of a screwdriver and see if that makes it work. If it does, replace the solenoid as that's just a temporary fix.....Dennis

On off air compressor pressure switch?

Is your air pressure up?

I don't have a regular horn but mine weren't working and it was the solenoid that was bad. Could be that or your switch to change over is bad.
