"Lean on me'

[Dan Osborne]

I keep hearing this song when I air my coach down now (92 Signature). Seems like the right side is going all the way down before the left. The left side only comes down when the last bit of air is released. Darn thing leans more than you would think before I put the jacks down and people start running over to tell me that I am tipping over , it just started doing this. Anybody got any ideas what would cause this?

There are probably 3 dump valves on your rig,

I have one mounted in the front center firewall and then two mounted on the rear frame above the engine. Each of these valves receive a signal to dump the air.

You may take taking the one off that doesn't appear to be dumping and check to make sure the air port that discharges the air is not plugged.

Also check the voltage coming to the solenoid valve to make sure you are getting correct voltage for it open. Possibly try bench testing the solenoid valve to make sure it is working.

I live in the SE and mud dabbers are known to plug holes like this. Last year I couldn't get air to my brakemaster system. I ultimately found that the quick connect port mounted on the front of my Jeep was plugged by a mud dabber.
