The air supply to the roof mounted horns on my coach , runs up the left windshield pillar, and the solenoid is attached to an air manifold below the floor under the drivers feet. I't the part with the white plastic cover in this photo. Black plastic tube running up to the top right of the photo is the air to roof supply.

Mine was basically right under the air horns on the inside top corner of mine... Had to rip the whole top panel that holds all the electrical switches for power for water pump generate hot water heater and everything out to get to it. And then it was buried in some insolation... Only way I found it was by accident. Air horns were not working so I thought air line we're clogged. Put some weights on the horn button and crawled up on roof to do some cleaning.. after cleaning and still no good I climbed back down and the cabin was full of smoke. The solonoid was smoking bc of shotty wiring... Avoided a disaster and found it....
Quabin, assume you own an Alpine since you posted to the Alpine Owner's Forum. Please add the year and model to your signature to aid other Alpine owners in helping with answers you have regarding your Alpine Coach. Your solenoid will probably be where rrthor describes, however with WRV it could be elsewhere. Disregarding responses from owners of other coaches will simplify your solution.
All others please return to the appropriate forum where your fellow owners eagerly await your wisdom.
