I have 4 sliders on my heater panel. I know what the top 2 sliders do-the windscreen/foot vents and the heat, but what doi the bottom 2 do? Or should I say, what are they supposed to do? And which one turns the rear cabin floor vent off and on? My VW handbook is in German. Although to be fair, I did buy it in Berlin! The van that is. Cheers

iirc the bottom slider switches the freah(cold) air to the top roof vents in the back and the rooe vents....... although, i'm not 100% as mine never worked anything.

bottom is mix - fresh left, recycle right and the third lever is the front/rear control, which conbined with the screen/foot control should allow you to keep passengers happy in the back.
