Not sure what your problem is but it's very similar to the one I've had more than once on my 2003 38 Open.. Here's what I found.. First the air compressor is located by the steering station, open steering station and there is a removal panel on the starboard side. Compressor is located there... My experience is not with the compressor but with the horns themselves. Go on the hardtop & remove the three screws holding each of the horn covers. Inside you will find a plastic (clear) diaphragm & gasket. Most likely the diaphragm is worn/dirty and the inside of the horns you will find dirt/salt... Clean all especially the inside top of the tube which forms a seal with the diaphragm... Sand smooth as that is what causes the diaphragm to vibrate, makes the horns sound... Do this yearly and my horns are fine....  Believe your horns are made by FLAMM, Fultone model 623511.. You can order replacement diaphragms as a kit 2132311 or at least I did several years ago.. You can google the horns: [Only registered and activated users can see links Click here to register].. Don't see the kit listed but I would call
