Air Leak UPDATE FIXED!

Hello all. I hope everyone had an enjoyable Christmas. Looking forward to the new year. To end this year, my coach decided to present me with a new problem. One that I need to fix ASAP. When the coach is idling, in drive, I am losing air pressure. Idling in gear at 5mph for a couple blocks and I will lose about 30psi. Driving at speed and the compressor keeps the air up but stopping at traffic lights and I can see the pressure begin to drop. I've blasted what fittings I have found and have located 5 small leaks which I will fix. The sixth is a pinhole in the front air tank so that will have to be replaced. None of these leaks are sufficient to cause the air pressure drop I'm experiencing. Further investigation revealed a possible culprit but I'm not sure how to proceed. With the coach idling, in gear, parking brake set, I can hear air escaping from the door air seal. I assume, (yeah, I know what that means) the air seal allows the psi to drop. What I don't know is how to trouble shoot it. So far, I've found no one that is familiar with how this seal works. I would guess there is a solenoid somewhere that controls it. Again, I assume it would have to be adjustable in order to control the psi to that seal but I could be wrong. I put a call into Monaco but I was 15th in cue so I left a voice mail and am waiting for them to call back. If anyone here who has had a similar problem and can point me in the right direction, that would be greatly appreciated. Thanks in advance....Dennis
