Desperate: Coach Only Airs Up On One Side

[Joel Ashley]

Norm, at least with HWH the control module is upside down on the ceiling of the electrical bay as Ron indicated.  Not sure about Valid, but if HWH is your travel balance control, that's where it should be;  immediately beneath the floor of the left drivers panel makes sense if, like mine, that's where your button panel is.

Norm,
Make sure the pass side height control rod is not loose and that the solenoid is actually being activated when you move the rod. (and BE CAREFUL under the coach).

This is going to sound really stupid but make sure the tag axle is down. The drivers side on our coach doesn't go up all the way if we have left the tag axle up. BCS told us that is common.

[Norm Green]

I checked the electrical compartment outside below the driver and there is no module there, I even looked in the dash access compartment but no luck.  When I move the passenger side height control rod, it does not activate anything.  I'll take a fresh look tomorrow morning.  Thanks again for all the suggestions and support, this group rocks.

Norm,

I read your post this am and so I looked in mine. The closest I can see are in the electrical bay:

One 20 amp fuse marked air level on one board
One 15 amp fuse also marked air level on another board;
A small separate board that has a 5 amp front level, 10 amp rear level, 5 amp for control pad, 7.5 amp for hydraulic level, and a 20 amp for compressor.

I know there is an emergency procedure for operating the coach outlined in the manual. I'm not suggesting you use it to move it, rather see if it does anything. If it does, then likely rules out mechanical problems, if not then likely as the techs have told you it is likely something to do with the control pad or the Valid system.

I took a fresh look at my problem this morning and did a variety of testing and observations based on the diagnostics manual the tech at Coach Net sent me.  I have a word document of those results if you are interested.  I have checked all the fusses in the electrical bay and found them all good.  I have attempted the emergency over ride with no results.  I will be calling Coach Net again to see if they can find someone to come out to fix this thing.

[Joel Ashley]

Norm, I'm surprised you didn't find the control module, but then I'm hardly familiar with all coach configurations.  Just as a reference, here is a photo of mine on the ceiling of the electrical bay:

I'm not sure I've ever seen a fuse in that bay... they are virtually all circuit breakers, including several HWH and leveler ones.

Joel,

That is an HWH unit. I had one like that on my 05 Patriot, but on mine and I expect Norm's they use the Valid system. I scoured the coach this morning and can't find anything that remotely looks like the HWH unit. Not saying there isn't but I don't know where it may reside.

Norm,

Coachnet or Valid may be able to help as it sounds like a systems problem if the emergency override won't do anything. It is Thanksgiving weekend here in Canada and I know Valid is based in British Columbia, but they
may have emergency contact personnel.

I'd take the control pad out and look on the back of it and record the model number. Also it seems to me that a light may be on the underside of it is properly powered.  If it simply the control
pad, then I expect Valid can likely get one to you quickly.

Joel, thank you.  I have nothing on the ceiling of the electrical bay.  I have also looked in the dash and found nothing.  I have two large storage bays.  In the first on, just behind the front tires, the only thing mounted is the solar control module.  In the second bay, just in front of the water bays, the only things mounted are my central vacuum, my surge guard and my Magnum Inverter.  I even took down the ceiling cover to confirm there is nothing there.  I also looked through the sliding panels where you access the water pump and in the electrical box in the engine compartment, nothing.

[Norm Green]

I contacted Coach Net and they checked and can't get anyone qualified out today.  They will attempt to find someone Monday.  When I spoke to Valid tech services, he said that I had a bad control pad and he also thought I had some other mechanical solenoid issues.  His only option was to sell me a new pad on Monday.  Looks like I am waiting until tomorrow.

Norm,
I think the control is in the ceiling of the first storage bay. You will have to pull out the slide tray, crawl in there and remove the screws attaching the ceiling panel. You will find the leveling control module along with several other modules there if it is like my coach. I recently had to find a fuse to the dash ac condenser fan and it was in a chassis control module located in the same place. My leveling controller is in the ceiling of that bay and I too have the Valid system. I have some photos if you think that would help.

Thanks Steve, I really appreciate the information.  I did check both storage bays but only took the ceiling cover off the back bay, not the first.  I will do that first thing tomorrow morning.  I would appreciate any photos you might have.

[Steven Link]

Norm,
Here is what I have there are several fuses and relays in this HWH leveleze. It is in the ceiling of the first bay under the ceiling board.  I think Monaco used a Hybrid form of the Valid/Powergear leveling. My coach has Air and Hydraulic leveling. This may only control the hydraulic part but I would still check all the fuses.

[Norm Green]

Steve, thank you.  I have found the unit, it appears to be just like your photo, including HWH on the side.  I will attempt to see what I can do now to restore communication and put the coach into travel mode.

[Steven Link]

Norm,
You are welcome! Please let me know what you find and the fix.  If you ever need to find it the fuse for the dash ac condenser fan is in the CCM in that same area. Took me and a very good tech at Link Automotive 6 hours for find it.   The sharing of knowledge on this board is invaluable.
