I'm currently setting it on windscreen and feet, however it's quite cold for my feet until the engine heats up and doesn't really do much to prevent the windshield from fogging up
And the reason I don't want AC enabled is because when the engine is cold, I can only blow cold air onto the windshield (obviously), and if I enable the AC on top of that, the air gets VERY cold, which in turn cools off the window to very low temperature. This means when I either increase the heat or disable the AC the windshield will fog up immediately.
On my previous Toyota Aygo, Honda Civic and my current Fiesta I can choose whether I want AC when targetting the windshield - the Ka is the first car I've seen where it's not optional but in fact forced.
Had I known before I bought it I would actually not had bought it, it is, for me, that big a nuisance.
Anyway thanks for your replies to the topic, I'll have to work with what I've got
