Hey all, my mate's A3, 2004 140 Diesel, is having a problem with the fans/blowers in the interior. Although on the digital display it shows if aircon is on or off via ECON button, it shows how fast/intense you want the blowers but there is no air coming through them. We tried selecting different options and can ear that all vents are opening and closing fine. Any suggestions please? Thanks guys and gals.
