Air Horn

[powersltc]

I have a 2004 Monaco Executive.   My Hadley air horns don't always work.   

I heard that I could attach a  horn button directly to the solenoid. 

Anyone know where the solenoid may be located on a 2004 Monaco Executive?

On my 08 Dynasty it was located behind the generator.   Replaced the solenoid and worked great for 3 years before I sold the coach.

Here's a tip regarding air horns. When you settle in for the night put a "chip clip" on the switch so it won't go off when the cat steps on the switch at 5 am like mine did.

Mine did the same until I replaced the solenoid and they've worked well since. The solenoid is in the generator compartment, passenger side on one of the vertical struts above your air drain valve.....Dennis

Thanks for the comments.   I'll try your suggestions.

Our 2 cats are gone now to be with their brothers and sisters in heaven.  But we have had that same experience when the cats used the steering wheel to climb onto the dash as night.  Stay safe, Stay well, Safe travels

I had a similar problem and found that the wire connecting the 12 V to the solenoid had loosened.  The horn worked sometimes and other times not.

Thanks.

On my Trek, I have to "wake up" the horn every day when I'm driving or else it doesn't work when I need it.  After hitting the horn button 5 or 10 times, it starts working and will give a blast every time I press the button.  I suspect the solenoid valve is sticking.  If I knew where it was, I'd try getting a little silicone in it's air line before replacing it.  I guess moisture builds up inside the air line over the years and causes problems.

Thank for the comments. 

 

I changed my solenoid and the horn still does not work.

Sorry to hear replacing the solenoid didn't fix your problem.  I found these cleaning instructions for the solenoid and figured I might as well post them for others reading this post.

Thanks Moonwink for this information as the air horn in my Dynasty has stopped working.  I will try this cleaning procedure as well as check the electrical connections on the solenoid as recommended by others. Thanks again.

A friend stored his RV outside.  Eventually the air horns failed.  We found that the horns themselves were plugged up by dirt dobber nests.  We sprayed water into the outlet of the horns, washed the nests out, removed the horn diaphrams and cleaned them.  After reassembly the horns worked once more.

Hello.

Ron P.  2004 Monaco Executive 

 

I changed out my air solenoid.  Tested the horn and nothing happened.   A couple days later,  I got on the road to go to Bethany Beach.   Hit the horn and it works.   I'll see what happens Wednesday when I pull out. 

Well, my horn is still working.   Swapping out the air solenoid must have done the trick.   

 

Thanks everyone for your assistance.
