hi guys I have a 128i 2010 convertible, I did change my window regulator in my passenger side, I disconnected the battery but now the automatic window drop is not working, before when I opened the door both windows dropped half inch automatically, and when I closed the doors they when up automatically, I looked some videos here in RU-vid in how to fix it but I can't get the doors to work. anybody had this issue before and how did you guys fix it. thank you for your help.
Try resetting the auto. Put the window up and continue to hold the button in the up position after the glass is all the way up for 10 seconds. That may solve it.
