When doing my regular visit and start up of my coach yesterday, I started the engine and shortly after it had been running for a few minutes I had a big air blow out. It sounded like it came from under the steering and dash area. As I am new to this, I couldn't figure out what just happened. After further review of my gauges, I found that the air pressure system gauge on the left side was empty. I take it that I had a air line let go. How do you go about searching for the leak/blowout? Is this something I can do or do I need a mechanic to work on it, I cannot move it at this point from its storage position.
