I had a similar problem on the air horns on my 2003 38 Open. What I found was excessive noise from the air compressor was due to the diaphragms internal to the horns themselves were worn out. Hard to believe but the diaphragms weren't seating correctly witch made the noise at the compressor. Changed the diaphragms and the noise at the compressor went away.. Surprise, surprise. Not sure if that is your issue or not but I would consider changing the diaphragms .. M2C
