bobdinsmore Posted June 22, 2022 Share Posted June 22, 2022 My air horn under the front hood is not getting any air. I found the solenoid (above the transmission controller in the left front bay). I hear it click but I hear no air. The solenoid is buried behind a spaghetti of cables and is a real pain to get at. I'm thinking I should remove the solenoid to check it out. Hints on how to test it? Has anyone had to get at this solenoid? Any other ideas? I appreciate any help. Link to comment Share on other sites More sharing options...
Ivan K Posted June 22, 2022 Share Posted June 22, 2022 Are you certain it is the air solenoid clicking and not the relay that operates it? I would have someone to operate the button and feel the solenoid. It's just too simple of a system. Unless there is a major kink in the line. Ours is fed through the same PPV as vacuum generator and step cover. If any of those work, there is air to the solenoid. Loosening the compression fitting on solenoid would prove it just as loosening the outlet would prove air to the horn. I can only talk to how our coach operates but assume same principle for yours. 1 Link to comment Share on other sites More sharing options...
bobdinsmore Posted June 25, 2022 Author Share Posted June 25, 2022 Ivan, thanks a lot. The horn now works: I think it was my error, but in the process I ofund the Step Cover now doesn't work so I'll have to take a look at that. Link to comment Share on other sites More sharing options...
