Yup, they work!! If by using them when I have no other lane to pull into, I can prevent having to lock down my brakes and throw God knows what all over my coach because some no driving idiot wants to pull out in front of my MH traveling 62 mph on an interstate highway at a speed of 25 without bothering to even look, so be it.

I was able to check the switch out with an ohm meter. All was ok there. All power to and from checked out with a test light. I found the solenoid and tried to activate it with a seperate 12v source since I was working by myself and couldn't check the wires with a test light upon button activation. I was unable to get the solenoid to activate. I ordered one on line at superior horns. I will be pulling the ole girl out of storage the middle of March for our Florida trip, and I plan to replace it then with a few other last minute repairs. I will let everyone know if that fixes the issue. This Pennsylvania weather is killing me.....c'mon March and Florida roadtrip!

I was a service manager for a large gulfstream dealer. most of the time, the problem was in the solonoid. moisture in the airline corrodes the piston in the solonoid. the solonoid is in the electrical compartment, which is the first compartment on the outside left side. first check the ground. if ok, jump a hotwire to the hot side of the solonoid. if the horn blows, the problem is in the wiring between the horn button and the solooid. if it does not blow, the solonoid is bad. rarely the horns are bad. you can check this by disconnecting the air line at the bottom of the solonoid and check for airflow when the solonoid is energized.

Everyone who had solenoid is correct. The weather this past weekend finally allowed me to get some repair time in. Thanks for the advice!

Good morning, I have a 97 Monaco Dynasty with HADLEY H00981 Air Horns installed and they are not working. I have not been able to determine where everything is located (solenoid or air source). Any help would be greatly appreciated.
Jim

The biggest problem we had with them, was the solonoid. When you press the button, it opens the solonoid and lets the air flow. these solonoids seize up because of the moisture from the compressor. Of course i am assuming the comporessor is working.

Thanks GA! I finally found the solenoid, it was located above the generator slide out, pulled it off and took it apart. It was completely frozen with what I will call calcium deposits. I cleaned it up with some 400 grit wet sand paper and put it back together. Now they work, I woke up the whole neighborhood this morning once I got them fixed!!! I've attached a pic of the solenoid for anyone else who might need it.
