I have a Sundance Optima. Jets work fine, but no air. There are three positoins on console for air and according to console air is blowing in all three positions. Also, no pressure in fragrance holder. Is there a way to bleed air system? Can it be plugged? My son had friend over, tub was so dirty afterward that I drained and refilled. Thanks

Your blower sounds like it is either bad or disconnected. Don't rely on the topside control for indicating air production. When your air comes on, you will know since it sounds like a shopvac running (they are essentially the same idea). If you don't hear that noise when you select air, then your motor isn't running and the source of the problem is found.
