My rear air bags empty within a minute of turning off the coach. Front stay up. It sounds like a valve opening. | ||

do you have factory leveling system? Where you level each corner seperate. or just the standard seated coach system with leveling valves. Bob | ||

Standard front is one valve and rear corners are seperate. The whole back dumps at once. There are no leeks. It seems like there is a dump valve that is automaticly opening when the coach is turned off. | ||

Your leveling valves in back are fed direct from aux air tank --no valve-- they have no valve between them and the bags. That said if you have level low the air travels from the leveling valves thru norgren valves before going to the air bags.These valves have o rings on them. also are controlled from front by a selonoid. that is the only other way for air to get back by the leveling valves. If you don't have it both leveling valves might be bad. Around that time prevost had problems and had a $1800 fix for it. not necessary. You can do it by re-routeing lines. | ||

They will be located outside the rear bay wall in the wheel well compartment. between the leveling valves.. The site I refered you to and the article will show all. Problem probably in front steering compartment control valve body. good luck ck out texas bubbler. Bob | ||

Oh well, My coach is setup differant. No 5 valve 2 here 2 there. Called Prevost service that was a waste. Think I will take a break and do something fun. |
