Air horn not working

[Coach_Cleats]

The air horn actuator on the steering wheel not working. Fuse is fine!Where do begin with the fix?

Have you checked the air level? You can find air horn fill up canisters at Pilot. It's usually with the jake brake and blinker fluid.

Air horn re-charge

Did it ever work from the steering wheel?

My air horns only work from a switch on the center dash, never the steering wheel button.

On mine the fuse is in the engine bay. 7.5 I haven't a clue where it would be on yours. Do you have the manual or can you get it on line. There may be a Safari group on irv2 that can help. Your fuse should be the same as mine, the 7.5 is maroon colored...Dennis

On my previous Class A, the Hadley airhorns required cleaning of the solenoid valve about once/twice a year. High humidity here, and the solenoid would get a little corroded inside. Taking it apart, cleaning it, and adding a little lubricant wasn't difficult, but got to be a bit frustrating.

Actually, in most set ups, the horn button is the GROUND for the solenoid with power coming to it from an "ignition hot" source.

Verify at the solenoid.

Find the solenoid and have someone press the horn button to see if it clicks. If it does you know it is getting power. Then go up on top and again press and hold horn button. Can you hear any air. If not either the solenoid is not working or something has built nests in your air horn. Remove the horn bell and look through. On my coach, both bells had insect nests. Fixed by poking the nests out. I now "exercise" my air horn on every trip to make sure the solenoid is still working and that no nest builders have been busy.

Just don’t do like I did. I didn’t turn it on with the ticker switch on the dash.

It’s a pretty simple circuit. Solenoid, switch and power. Horns can clog. Solenoid not working or bad ground/switch.

I’d find the solenoid and check it for operation.
