Make sure Eco isn't turned on, make sure re-circ is off, make sure ACC is on, and fan speed to at least the middle auto setting. If you still have issues then start searching around the boot and footwell carpets for any signs of water ingress.

 

I found that just being patient with Auto mode gives me what I need. It takes it 20-30 sec and all goes clear for me

 

And don't set the fan speed limit to low. It's a limiter on how high you want the automatic fan to go when it wants to push more air

 

ACC is key but I do find if driving into cold air the warm moist air inside the car condenses on the windshield. I find this happens as my car leaves a warm garage and then gets up to speed with cold air chilling the windows.

 

I have experiencing that too here in the Pacific Northwest with our wet winter, but I have been using the eco mode on auto most of the time, the back window and the driver side window near the mirror area are the spots with more accumulation. I will try turning off the eco and see if that helps.

 

Are you just turning up the temperature or are you using the front defroster. When I hit the defrost button next to the volume knob it clears any fog almost instantly. Yes, the temp is set to high but I just lower it to 72 or 74 and leave the defrost on with eco mode and it works great.

 

This is most effective/comfortable, the fan can be the lowest setting and it’s still able to clear at a lower temp with recirculate on. Window fogging is definitely a design flaw they didn’t tackle very well.

 

I've been getting more windscreen fogging recently, and the max defroster doesn't clear it at all. When I think back the max defroster has never been effective in my car. There's plenty of increased fan noise when I put max defroster on but there is absolutely zero airflow felt anywhere near the windscreen, not one bit. Does anyone get airflow out of the vents circled below??

I've got nothing coming out of any of them, regardless of whether I use the max defroster or taking climate out of auto in to manual and directing airflow to windscreen only, and increasing fan speed.
