Thumbs up Aftermarket horn...

"they put in a different horn,like a regular car horn...that will not do..i want to restore the original sound.."

Does it work when stock horn button is pushed?

If so you can wire a new horn thru the same relay.

On our Burb I used a Grover air horn from a fire truck. Wired thru an on/off switch under the dash to the flash to pass switch on the steering column and back to the solenoid on the pressure line for the horn.
The stock horns still work as designed.

The air compressor wired to an un-used switched 30a breaker at the under hood PDC, black box just below the horn.

la nomade- Here's how the AIR Horn is set up on my 1990 345LE.

If your sitting in the driver seat and swing your left foot all the way left you'll hit the 'kick' panel carpeting. Behind this carpet you'll find an air/electric solenoid that has two air lines, one comes from from your air tank for rear suspension and other one goes to the roof mounted horn. Then two wires on it that go to a horn relay. So basically even the AIR horns are also part 'electric'.

On the AIR side of this solenoid they are famous for sticking either open or closed. When they stick open you can't stop the horn from blowing and when stick closed they wont allow the horn to blow. I would take mine apart and lubricate it but after having to do this twice I ended up buying a new one that has been OK for a while now. Condensation in air lines is hard on this valve that's inside the solenoid.

The electric side is fused for protection. On mine it's the same fuse as the cigarette lighter. Regardless, naturally if the fuse is blown, no horn. Finding what's blowing fuse will correct this.

If your problem is intermittant I'd look at this solenoid first. As Bob mentioned above they are more or less universal so you dont necessarily have to go to Airstream for the part. Any decent RV shop or auto part store should have one. Here's a pic. of mine.

Keep us posted.

Chronic problem...

Those air valve solenoid's can be an ongoing problem.
On our 95 Burb I mounted the valve assembly close to the compressor in an area that allowed the condensation to pool around the plunger, required frequent disassembly cleaning and eventually replacement.
On the 06 it's mounted vertically & further from the compressor and tank, three years and no problems so far.

Agree......Reminds me of one time we were sitting at a red light when a motorcycle stopped next to us and the rider motioned to sound the horn. So I did, only to find it wouldn't stop. After maybe a minute the valve closed. It's funny now, not then though.

oh,dear me...i hope this will not happen to me, once fixed..as soon as it is, mid may or so ,i will let you know..this all is very helpful,at the garage,they are in a hurry fix things the easy way,not restoring....big differece...closest air str.garage is hours away in new jersey....now,nor my radio or back up camera is working,all that was connected to the same fuse where he now put wires on for the regular car horn...a mess.
i should stand there and watch what they are doing.
same with my back up lihgts,i smasched one backing up on a pile of rocks,instead of ordering a new same one,they put 2new ones round,black,and ugly having nothing to do with the style and integrity of the air str...need to replace those. thank you all....M.

Leaving a rally...my own in conception, and when I hit the horn button on the steering wheel; i just blasted for about 30 seconds..I beat on the damned thing for about another 30 seconds...it quit. and hasn't worked since...I KNOW how to impress people, and as Trailer Trash Queen, I will continue to dazzle you...your remarks are anxiously awaited...m

For what it's worth I have found that I can not "toot my own horn" when I have my tilt wheel fully raised. If I lower it one notch it works perfectly. I am guessing raising the wheel causes the contacts to become misaligned. Maybe (don't take this too seriously) Airstream or Chevrolet engineers designed it this way so my dog can not honk the horn when he puts his paws on the steering wheel to bark at passersby when we are camping. Those engineers think of everything!

thanks to you very specific and clear explanation,it was easy to find its location,had to lie down,face up to take things appart,very unconfortable position,and it turned out that the solenoid was fine,clean and dry,it simply had a bad electric connection,so to my great delight,it is fixed.....thank you....now i am dealing with the radiator fan not coming on...waiting for a new clutch.....best,M.

How's your trip home so far? Derek
now that it has been fixed,i should tell you that the horn on my A.STR.is both electric and air,it depends on the compressor in the back as i thought,thanks to this forum i could actually locate it,take it appart,and..fix it,it was a bad electrical connection,not the selenoid....one more thing fixed.....

Martine,
Thanks for the 'heads-up' on air horn. Seems as if only one of mine on roof is working. By reading the rest of this thread, I now know where to start looking.
Thanks, Derek
