Opened the passenger door first thing this morning and the window opened half way not the normal slight drop. Closed the door and the window closed fully, then opened drivers door but window did the slight drop as normal. Strange I thought so drove into town and parked up, on return the passenger side did the same again but this time the drivers side half opened as well. So decided to do a reset and opened and closed the windows via the key fob, seems to have done the trick but will keep an eye in it.
