Flap above aircon filter - position?

[komichal]

General advice is - when you want to drive somewhere and the car is incredibly hot and even hotter inside - to open all doors and let the wind and nature cool the inside as much as possible. After a minute or two you can start the AC and let the air circulate internally - only after a few minutes (when the vents actually start blowing the cool air and the internal space starts to cool off) you can consider switching to external air.

The AC unit in Yaris is quite weak I must say. The dealership checked the coolant, the pressures, the compressor - everything OK. But it takes ages in hot summer to cool the internal space. I wonder if the more southern regions received some more powerful AC because in hot days in Central Europe the AC is almost insufficient.
