Hello,

When it gets very chilly outside, you will want heater to go to the floor vents to keep your feet/legs warm but you get cold air coming to the floor, but your defrost mode or vents blows very hot air which means you will need to press Recirc and press AC buttons and hold both until AC flashes (3-4 seconds to make it flash) then you let it go. The flashing will continue for 5-10 seconds at most.

That will force itself to reset the blend doors to the right mode then boom, your floor vents gets very toasty hot quickly like it should when you turn the knob to the floor vents.

same thing with my 2015 Passat as well. wish I did this a long time ago with the JSW, was thinking the heater core was going.
