2007 Monaco Caymen xl 36pdq Air dump switch won't dump the air

My air dump switch won't dump the air can someone give me a few points on how to trouble shoot it?  Thanks.

On my 2002 Windsor I have a 15 amp fuse in my front drivers side electrical bay for the air dumps, that would be the first check.

If you are only having trouble with one dump solenoid you should check to make sure the connections are good and that you don't have blockage in the exhaust port, mud dabbers are notorious for stopping these up.

For my rig, I have to have the key ignition "ON" to dump air.  If not that, go with Jim's advice.  May want to check voltage at the dump solenoid when switch is depressed.
