Hi all, left the car for a couple of days then needed it to move some stuff, guess what - the tailgate door will not open. Use the handle & the window drops as normal but the door doesn’t open, there is a slight sound like it’s trying to do something. The window operates normally from the inside switch & closes when using the key in the tailgate handle. After the window has dropped if I bang the handle the window goes back up. Boot light works fine too. Sure I need to remove the tailgate door card with the door shut but not sure how - seen many posts but nothing clear. Any help much appreciated
