I had a similar problem when I first purchased our coach, turned out the 120 compressor was not making any pressure and neither was the 12 volt compressor. Check and see if your compressors are making any pressure, I did this by simply disconnecting the air line exiting the compressor and placed my finger over it while running and it had no air pressure at all, same for the 12v. If you have pressure at the pumps, then you must have a large air leak somewhere. Good Luck
