Angry Soft Close + Auto Window Problem

Hey guys,

Recently my coupe's passenger door soft close stopped working and the windows don't seal when the door closes. Upon opening the door, the windows go a 1/2" down as normal, but not up when the door gets shut. Then, if I hold the window button up 1/10 of a second too long, they open a 1/2" again! As you can imagine, this is driving me nuts!
It seems like some kind of logic error, not a mechanical failure, or could be a combination of both. Anyone had this happen before?

You probably need to reset the limits. Open the window and hold the window opening button for 10 secs after the window is fully open then close the window and hold the window closing button for 10 secs with it fully closed. That shoudl fix it

The reset procedure worked, but I don't know exactly what the actual procedure is. It took me around 4-5 minutes of playing with both windows to finally get all 5 automated actions functioning normally.

Thanks very much for the clue. I thought of a limit reset, didn't know the procedure and dismissed the idea because I convinced myself it wouldn't fix the soft close. Anyway, all's well that ends well.

Thanks for the procedure. I'm not sure it's that simple because until I started messing with the back window, then the front again, then the back again and on and on, somehow it eventually reset. Hopefully this archive will be completely useless. LOL.
