Rear side window won't raise with Roof - DB9

[CasualBrowser]

Hi All,

Have recently started a DB9 which has been off the road for a while. Had to put a new battery in it. Everything seems to be working OK except for I can't get the right rear quarter light (no idea what it's called) window to go up when I close the roof. Has anyone had this or have any idea what it could be? Thanks in advance.
