Air solenoid question - 2005 HR Navigator 45 ft. Located in area of rear tag axle. What is it and what does it do and how does it work? Thanks

I have a 2005 HR Navigator 45 feet DD 515.  Does anyone know what part of the air system this part below, works and how can I buy a new or a replacement part. I have two of them.

Air Dump Solenoid is my SWAG

Test by airing up the system and then have someone press the air dump button and see if the other purges air.

Is this the air dump button on the lower rail or on the 2000 pad? 

[jacwjames]

It should be either on the dash or side console.  This is the button you use to release air from the air bags to lower the coach.

Check your prints.  Sometimes the PN is on the prints.  Check or download our parts list,,.,probably in there as well. Look wt the prints and connections to answe your video questions. These are not a special valve.  Just a closed with no power….energize or provide power….coil then opens up the valve.  There is no need for an outlet hose or tube…but add one if that makes you happy.

Good Luck…

It’s also possibly the control for the tag lift. The tag axle will have a normal leveling and ride height set of lines to the air bags, and will also have a separate set of smaller air bags to raise the axle when the driver armrest switch is activated. Basically, the switch is wired to the leveling system, telling it to dump the tag axle air bags and inflate the bags that raise the axle a few inches.

I looked on the parts list file and did not find the  solenoid or a part number.
