OK my brilliant money saving fix didn't last long. The brushes seem to be disintegrating on the blower motor. I can clean them up and it'll work for a week, but ultimately fail again leaving me without aircon. Both Audi & VW say there are no serviceable parts on the unit and are asking £262.70 for a new fan unit. I can get one from "Audi 4 U" for £170 (apparently OEM part). But all I need are 2 tuppenny hapenny brushes. I've tried breakers yards but there's no guarantee that the fan will be any better. A guy on tyresmoke replaced his with ones from a washing machine motor so I might give that a go. Any bright ideas?
