Good working unit.  These frequently fail, and cause nonoperational dash vents, as well as vacuum leaks under the dash.  Hear a hissing under your dash?  Center vent intermittently shut off?  These are some symptoms of a defective distribution switch.  These cost over $100 from Saab, and have recently went "no longer stocked".  This is a good used unit, fully functional.  These are located on the rear of the dash fascia.  It engages to the selector switch.  Changing them is fairly easy!
