So, I'm getting the dreaded book symbol, and I suspect that the distribution blend motor is bad as I only get air from demister. \n\nReading the forum, it appears that most of the blend motor fault has to do w\/ the internal gears losing couple of teeth. \n\nAre there anyone out there that sells just the replacement gears? Possible business opportunity for Shupack? \n\nI'm thinking used blend motors are like $120-$200. Replacement gears would be like $20......Just dreaming, I guess.
