I have a 2005 325i - the Drivers AUTO-Window down no longer works. It will go down manually (holding the button down) but not automatically. I have tried the sync fix: "Open window, then hold down the window button for 10-30 seconds, then up and hold for 10-30 seconds. I have tried every combination I can think of but no luck. The Auto-Up works fine. The Passenger auto works fine. Any thoughts? New Window switch? Thanks everyone!
