So the coach had been working fine, and this morning when we got on the road after parked over night the coach was driving very bumpy and noticed the steering seemed strange, so stopped and noticed the coach is all the way down, and the bags are not airing up. Not really sure where to start looking, I can hear the air pressure relief open when it gets to pressure and I know the system is airing up for brakes and the tank reads 120psi at the gauge, I cannot hear any air leaks, even with the engine off. I would imagine the "dump valve" being open would really let a lot of air out if and this would be audible. My levelers do not work, so I cannot use the HWH system to raise the coach. It seems like the valve to let air in to air up might not be opening, if that is a thing, maybe this is the same as the dump? I'm not even sure where this would be on the 1997 Marquis with the Gillig chassis. I did a brief search but didn't come across other posts like this yet, and with the urgency to get it moving I didn't have time to invest in googling it more. I'll keep poking around and pull out the Gillig chassis manual here in a min to ee if they show any trouble shooting.
Thanks for any pointers.
