air bags on left side flat can't drive
 I have a 1998 U 290 motorhome and my wife and I started to leave in our motorhome this morning and the front and rear air bags on the left side did not have much, if any,  air in them.  The right side bags are inflated making the coach so low on...

The emergency leveling procedure linked by Doug (above) assumes a faulty leveling (height control) valve.  There are 3 of these valves on your coach - one in front and two in the rear.  The two rear valves control the height at both corners in...

Thanks for the advise i will be trying it in the morning.  One thing i found out tonight messing with it is that when this first started this morning i saw that the left side was lower than the right but when i started the coach, which had been...

  We drove a few miles and i noticed the bottom air pressure gauge losing pressure dropping to about 90 psi and then it would pump back to 110 psi and start slowly losing again. 

John,

The travel mode light is on even with the coach sitting on the tires.  If i try to level the coach in the auto level mode it does nothing.  The travel mode light goes out and the "air light" comes on but nothing happens.  If i go into the manual...

John,
There are two parts to this HWH system.
The travel system that only uses the top solenoids on each manifold. When the green travel lite is on you have power going to all four travel solenoids holding them open so the ride height control...

THANKS EVERYONE FOR THE HELP SOME HOW I HAVE TO GET IT TO MHT.



Your profile says you're just north of Longview, TX, correct?  Just so we know how far (and what kinds of roads) you're dealing with.

I am located on Highway 271, Pittsburg, Tx  which is about an hour north of Tyler.

Thanks,
John

John,

If you are not able to regain control of the 6-pack valves by using the touch panel, and still want to get the coach moved to MOT (or where ever) then I can only think of two solutions.

1.  Hire a towing company that can put the whole coach...

Peck on the down side ride height valve pretty good.. take lever loose and work it up and down.. May have already been mentioned but worth a try and I've seen it work before on air ride.

The air leak could be the cause of the airbag problem.

Have a YOUNG man that has a foretravel and he is going to come look at it this week.  I have seen him fix things that stump a lot of people on Motorhomes.  When we get it fixed i will post the results here and again thanks for all the help.

Latest info we did find a busted airbag on the rear left and we are going to try to replace it.  We also did get the air leveling system somewhat working but are going to have to get the air bag fixed before we can do much else.  Clamped off the...

Tubeless tire repair plug will usually cure the problem until you can get a replacement. The hole usually faces the tire and was the rear bag on the left rear on ours.

Mine was the rear bag on the left and had an area about 1 inch tall and 2 inches long that was just rotted and really no place to patch.  We got the old one off and the new one is supposed to be here tomorrow and hope that fixes the problem.

If you have had problems with the leveling system all along, it is well worth your time to send the control box back to HWH. Surprisingly their turn-around time is pretty good (3-5 business days). I took pictures of where the cables connected,...

I now have the coach back level again.  The problem was the left rear air bag and we replaced it yesterday and the coach is now level and in the travel mode.    As far as the leveling system not working i seem to have maybe fixed it also. ...

however I think i also have a stopped up dump line on the front.  If you have about 20 min to hold down the dump switch it finally goes back into the travel mode. 

John,
