Definitive window reset procedure.

Definitive window reset procedure.
Too many different instruction out there telling you to hold you window switch for 15 seconds, and lack of explanation on how to handle the switches.
Here's a proven method based of the Service Manual:
The trick is to "hold" the switch on the way down, do not hit the switch and let it "auto down".
You do not have to hold it once it hits the bottom.
Once it hits bottom, "hold" the switch on the way up, that tells the BCU you have hit bottom, and returning up.
Do not use the "auto up" function, then keep holding it for 3/THREE seconds, not 15. You will hear a distinctive sound when the auto function has been calibrated, it's the BCU cutting power to the switch because you're at the top.
The 3 seconds is to tell the BCU you have reached the top.

I have a problem with my passenger side window on a 2011 G37S coupe. Every time I open the passenger door the window drops about a half inch. If I close the door and reopen it....it drops another half inch. It will keep doing this as long as you keep closing and opening the door and does not roll back up on its own.
Anyone else come across this problem? Will this procedure fix this problem?
Thanks
