I've just noticed that the top few rails on my new (old) 2014 don't work. on inspection , it looks like one of the wiring blocks connecting to the screen may be missing, as it looks like there should be three, and I only have two. Not sure if this is the case with all of them, though. Is anyone able to check at the top of the screen and see how many wiring connections there are?

Not specifically your car , but it’s possible some of the top lines are part of the radio antenna system and don’t actually heat up .

Interesting observation. They don't seem at all electrically connected to the ones which provide the heating. Maybe this is the reason :)
