Heated Front windscreen on L322 2006

Hi Folks
I'm hoping someone can help, I have a 2006 RRL322 and the front heated screen only works for the near side and not the offside (UK Model). I am struggling to get to the screen connections. I removed the scuttle panel but no cables here apart from wiper motor. viewed you tube to remove dash but panel close to the screen on the inside didn't appear to be removed in this you tube tutorial. Is this where the connections are?

Also I have tried to track down the fuses and relays that are spoken of on other threads, but again I 'm unable to track these down. I have a enclosure in the engine bay housing fuses and relays but none for the screen and I have a fuse panel located in the glove box again no sign of any relays.

appreciate if anyone can give me a steer
thanks Kev

Mine is 2004 and I believe the screen connectors are behind the A pillar air bag cover, ignition off remove air bag badge, remove torks screw pull top of cover towards the mirror to free it from the clips then lift it up, pretty sure I have seen them under there as for relays cant think where they are (might even be rear right fuse board) what we need is somebody like @Saint.V8 to pop in here.
