We have a 2004 42' Monaco Dynasty with a tag. Recently the Tag started to not lift when I press the tag lift switch left of the drivers seat. I have verified that I have 12 v to the air valve that releases the air from the tag so it will lift. I can hear some air being release but the tag does not raise off the ground.
Any ideas on what might be wrong or what to check will be greatly appreciated. Is there a way to verify that the air valve is function properly? This is separate valve from the one that adjusts the down pressure of the tag.
