Air Dump

I am experiencing a problem in dumping the air in a 2004 Holiday Rambler Endeavor. When holding the dump valve in the open position on the dash, I am experiencing that the driver side air bag dumps first and then the passenger side will come down later.......Any suggestions to have them dump evenly? Appreciate your comments. Thanks.

The valve may be sticking and may just need to be operated more frequently. Be sure to change the air filter/drier every two years to ensure the air is staying dry and you should not get sticking air valves. Lubricate the mechanical ride height valves with dry silicone when you lube the chassis. Good luck and keep us posted.

You also have some relays in the compartment below the driver seat - those are what actually activate the solenoid valves for the air system. I think there are two, though, front and rear. Never heard of one that did only one side. I'm thinking Mike;s suggestion is more likely - a sticky valve on the passenger side air bag. Supposedly easy to replace, but I've never had to do one. If you aren't adventuresome, this is the sort of thing that any heavy truck repair facility can do in their sleep. There is nothing unique about the air suspension system in a motorhome, so no sense paying RV parts and labor prices.
