I have a t6 kombi swb highline. As far as I was aware all the vans now have heated wing mirrors? So the first morning with dew I got in the van, cleared the windows with the front and rear heaters and wipers and pushed forward the little mirror adjuster to set the mirrors clearing like they used to in the old T5. But nothing happened, nada, zilch. I tried other ways of pushing the button but no cigar. So my question is.. Am I just being dim? Has my van been delivered faulty? Or am I misinformed and the van comes with the icon for de misting but not fitted as standard to the Highline?
