Front Air Suspension Problem

I have a 2003 Allure which recently developed a problem with the front air springs leaking down completely when the parking brake is released and in the travel mode. The two front warning lights illuminate. The coach is not equipped with jacks.

I have cycled through every function both automatically and manually, and the coach levels when the parking brake is set, but immediately leaks down when brake is released.

I replaced the height leveling valve, and it seemed to work fine for several minutes with the brake released, then it started to leak down again and the warning lights came back on.

Is there a reset anywhere, or does anyone have any suggestions?

I have called HWH 3 times and have left messages but have not had any luck getting a tech to call me back.

Thanks,
John

Hang in there for a HWH tech. Sounds like a problem going into the travel mode.

it sounds like a bad chassis dump valve. with the engine running, and the park brake released, the hwh system is disconnected from the chassis. the hwh system should turn off and travel solenoids open to travel. check the fuse for the hwh travel solenoids. all hwh solenoids valves are normally closed. there should be a tee handle on the side of the manifold. this will allow the unit to go to ride height. download a service manual for your system at hwh.com its free, and has a step by step to diagnose your problem. a return phone call is going to take a while. a lot of coach owners are repairing their own coaches. if you do a diagnosis yourself, the tech can give you a quicker answer, and get parts coming.
after diagnosing, try emailing them. these seen to get a quicker answer.

I got the front air suspension fixed!! I had replaced the front height leveling valve which had not fixed the problem. I contacted a very knowledgeable tech from Motor Homes of Texas at the suggestion of a friend, and he told me to try rotating the actuator arm 180 degrees. It worked! Thanks for the replys to my problem.

It is not a well known fact that you can install the ride valve 180 out. Now you will be ready when the next one fails.
