So I have a new problem with my 07 navigator, when I originally bought the rig occasionally the right side of the rig would air all the way up I could manually deflate it it might do it a second time and by the third time it would level itself perfectly. Now the left rear airbags fill constantly, until the right height valve is bleeding air off even while driving. Looking for suggestions or anyone who’s had this problem before. The right height valve I know adjust how much air goes to the bags or is emptied from the bags. Could it be that this valve is just stuck open on the inlet side.
