Started the coach the other day push the horn level and the air horn came on but would not turn Off! Push the lever several times, still on. Found the fuse in the compartment below driver seat pulled it along with wire going to the relay, still on? Needless to say the air pressure does drop. It seems that an air switch is stuck open? Any suggestion how to bypass for a temporary fix? Location?

The solenoid should be in the compartment below the driver. Disconnect and block the supply line.

If you do that, would the air from the system keep bleeding off not allowing air breaks to work? Would set of vice grips on this air line be a safer choice? Vice grips and zip ties make the world go around.

Does anyone know the location of the Air Horn Valve on a 05 CC Allure? It is NOT in the compartment below the driver seat.
Thanks for you help.

On my coach the air horn solenoid is located adjacent to the electrical bay in front of the driver's front tire accessible from under the coach.

That is the reason I said block it off. A 1/4 pipe cap works well on the air fitting in the solenoid.

You might try banging on the solenoid with a small hammer too.

The domestic hot water is scalding hot.
I seem to remember this subject being discussed on this forum, but have been unable to find that thread. It had something to do with a mixing valve being stuck. Can anybody tell me how to identify that valve, if that is the problem? And, once I locate it, is the un-sticking procedure any more complicated than whacking it with a hard object? Jim Biestek

The valve is on the side of the box & has a gray plastic knob on the top. Screw the knob down and back out a few times and see if that breaks it loose. We had to replace ours after after 5 winters of Ajo, AZ water.

James, if you go to GOOGLE and type in Honeywell Mixing Valve several photo's will come up to show you what the Valve looks like.
But Jim has given you the probably fix.

I'll try that first thing in the morning. Does it make any difference if the water is hot when you do the knob turning? I know it has to be hot to find out if it worked.

Use a cooking thermometer to take measurements at the closest tap.

The air valve was in the compartment behind the front bay which was accessible with the generator out. A pair of vice grip took care of the problem.
Thank You all very much for your inputs.

There may be two different issues here. Based on these messages, I went out and tried to turn my mixing valve and it was definitely stuck. Took a pipe wrench to break it free and then it freely turned through its adjustment range. Is this the issue or is the valve stuck internally? In my case a whack would not have solved the problem. My valve had a gray plastic cap and there was also a yellow manufacture's tag still attached.

It may be stuck, ours was and we replaced it. What I would do first is flex it several more times and have the hot water running while you do it. I try to do this every week or so.

Jim - Here's my BS on the Honeywell antiscald valve: http://www.muniac.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=95#Post95 (http://www.muniac.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=95#Post95)
I wouldn't go in there with hammers and force. A really bad idea.
It you break the heat exchanger line feeder tube off the Hydro-Hot it's an expensive repair. The valves can accumulate sediment. Usually this causes cooler water but I guess anything is possible. I changed the plumbing on my valve to make it easier to service/replace and avoid the possible heat exchanger damage. I took the valve out the other day and cleaned calcium and sediment from its guts. It came apart reasonably easy. Used a cotton swab and vinegar. I also applied some DuPont high vacuum grease to threads and seat. The grease is stable to 400F. The valve's seat is teflon coated. A somewhat 1/2 assed attempt at preventing build up. Those valves don't last long either. Some say 5 years others say less than that. It depends on how bad your water is.
Arizona would be a good test case as their water is horrific!! We use a water softener which I think is a good idea. As for the valves, I can't say I'm impressed with this approach. It's another quick and dirty approach to idiot proofing the world. And it seems in your case the valve isn't preventing the scalding situation it was designed to.
You might want to go ahead and replace that valve. Removing the valve is a tricky repair so be careful. The idea is to remove it with minimal stress on the copper Hydro-Hot lines. Also make sure to exercise the setting knob once a month to avoid it from binding.

Thanks for that. It is a very informative web site- certainly saved me from some expensive missteps.
Everything I've read tells me that a failure of the mixing valve will result in lack of hot water. My problem is exactly the opposite, but I can't think of any possible cause other than the mixing valve. Does anybody know of another possibility?
I found that the knob on the valve was frozen. After removing the expansion tank I was able to get a tool on the knob and free it. It now turns OK, but does not affect the water temperature in any way.
An earlier response gave the model number of the Honeywell valve, but the message is still on my computer at home (we are now passing through Las Cruces on our way to Denver). Would whoever sent that please resend it to me?
Also, what is the web site of a support group for Hydro Hot?
I would also welcome any other comments from this august group.

That would be Roger Berke Hydro Hot: http://forum.rvhydronicheaterrepair.com/forum.php (http://forum.rvhydronicheaterrepair.com/forum.php) When mine had the same symptoms, I exercised the valve several times and then adjusted the temp with the hot water water running. You might be in for a valve replacement. Good luck,
