Hi guys thought I would share a problem with you I experienced with my 370z windows and the remedy.
I disconnected the battery and found my windows failed to go back up when door was opened, therefore if you opened and closed the door a dozen times they ended up being completely open (not a great security feature).
The remedy was to turn the ignition on/off within 2-3 sec whist holding the door window control down 4-5 times, both windows required to be done one at a time. Repeat as required is unsuccessful.
The sync now working as perfectly and car now secure.
