One of many ongoing issues. I did some reading and research, several of the old threads are locked.
Airhorn will not work and step cover will not slide. I've read both are tied pneumatically.
Here are pics of my electrical compartment located left and below the drivers seat. Any idea which blue lines go to what and any trouble shooting on this would be helpful. I was told the airhorn works off the steering wheel horn. My old coach had a regular horn on the steering wheel and a switch on the dash for the airhorn.
On the bottom picture, I took the blue tube off and there was no air coming out of it when the rig was running.
Also, when attempting to honk the horn, no electrical noise was heard in the electrical compartment.

Re: Airhorn and step cover
I've watched all three of these videos:

Its a great review, I probably won't build my own manifold, but it was very helpful. My chassis service center is an oily mess and the video presentation states exactly why.

Re: Airhorn and step cover
My mechanic as tracking down the airhorn and stair step lines.
He found these two lines which go to the step stairs, severed. He cannot find the opposite ends.

Re: Airhorn and step cover
The mechanic replaced the horn solenoid with one from NAPA and the horn worked really well. So well it wouldn't turn off.
He has asked me to find out if anyone can provide a part number for a hadlely horn solenoid....
This is what i found off of the Hadley website:

Re: Airhorn and step cover
I don't have part number, but any air solenoid will work, as long as the design of the solenoid is to open the air valve when energized. It sounds like the solenoid he obtained from Napa is either opposite or the solenoid got stuck open, or maybe you switch in the horn button is stuck on. This could be easily tested with a volt meter.
My solenoid has not visible number, but it is made by Grover Products Co. and this is the only electric 12v solenoid valve they offer. Mine looks different than what the currently have, but the function should be the same.
BTW, if the old solenoid still energizes internally, it likely just needs a good cleaning. All the gunk you have in the airlines will often bind those solenoids up, clean them up and most of the time they will work like new.
As for the "severed looking blue air hoses for the steps, those are likely vent hoses to release the air inside the air cylinder of the step cover it opens and closes. It is the same concept when you hear rushing air when air brakes are released. If the air can't escape the cylinder won't be able to move in either direction.

Re: Airhorn and step cover
Replaced the solenoid and horn works great.
