Hello, new guy here looking for some knowledge. We have a new to us 1998 Monaco Dynasty. Today while we were letting the motor home run I could hear a loud, constant hissing of a air leak in the front. Crawled underneath and tracked it to a air line block(?). The block has two wires to the top, 2 air lines, and a brass fitting which is where the leak is at. A 7/16" socket fits it, diameter is about 3/8", and it is about 1/2" long. It appears to have a stone type filter in the end?
I looked for a line that may have blown off but see nothing. I do have pictures and will try to link to them or post them in this message. Could this be normal to leak air all the time? Could it be a vent, and something wrong inside the block is actually malfunctioning causing air to shoot out? The only thing air operated that I'm aware of that doesn't work is the step cover return. Thinking about it now I guess I should have flipped that switch to see if it changed.
I will try to get pictures here somehow. If I can't, I apologize. Thanks for any help.
