Early afternoon I went out to the coach and raised the coach up to a higher level with the Air Bags as I had planned on changing the fuel filters and checking a few other items out. I have done this several times in the past and have had no problems. Something got in the way and I never made it back out to change the filters.

After supper I went out to lower the coach back to the lowest level as that is where I normally have it when it is parked but the front would not go down all the way, not even sure it went down more than inch if that much. The rear of the coach does go down to the normal deflated level. I hear air being exhausted in the front but the coach only moves down a inch or so. After a while, the normal time that it takes to lower the coach, there is no air being exhausted but the front of the coach is still well above the level it normally sits when I deflate the air bags.

Too dark now to do any more troubleshooting so I will dig out the schematics and start looking at what could be the problem.

Anyone else every have this problem?

Any suggestions appreciated.

Do you have the HWH Air Leveling system? Is that the panel/button your using to raise and lower coach?
If so, what happens when you press the "Travel" button?

If you don't have HWH air leveling, what system do you have?

Yes, I have the HWH air ONLY system and yes I am using the panel to raise/lower. We have had this coach for 8 years and this is the first problem I have had with the air leveling system.

Travel goes to a green light after a few moments, but the coach does not go down, it is still 6 inches or so above travel height!

I called HWH this morning but they are on a call back basis right now and my number did not come up today, so I got the schematics out and tested all the fuses and the relays on the main board and all are good. My thought right this moment is the right front solenoid valve is stuck as that is the only point that will not lower other than about 1 inch or so.

I am hoping I come to the top of the list in the morning or the coach will stay home this weekend as I am not crawling under the coach and turning the T-handles to bypass the travel solenoid valves, which would put the coach in travel mode while I was under it!!!!
