I Recently purchased a 2004 Monaco DIplomat 40 PDQ and found that the air dump switch will not activate to lower the chassis before lowering stabilizers. Any thoughts or suggestions would be greatly appreciated. Because the Roadmaster chassis that the coach sits on is no longer made I have found getting service and repairs to be an issue.

Thanks for any help

My 2002 HR dumps VERY SLOWLY with the dump switch. Just pump your brakes with the engine off and you will settle on down much faster!PSSSHHHH PSSHHHH PSHHHHHH

Yes, the Dump Air solenoid on older Monaco's is very slow and is sometimes hard to hear. But, pumping the brakes will indeed exhaust the air in both tanks very quickly. But that does NOT empty the air bags. The air bags have just 3 ways to dump.
1. They are defective and have a hole[emoticon]
2. The Ride Height arms must be moved to dump the air
3. You use the Dump switch
When you exhaust all the air, and if your manual dump switch does NOT work, extend the leveling jacks. Once they hit the ground and start to raise the RV, the ride height arms will move and they will dump the air. Once that has happened, retract the Jacks and do a 2nd level. That will keep the motorhome lower to the ground. Doug
