OK, we can agree to disagree. I just think that you would be better off to just quit fiddling with it, leave it in the neutral setting (no coloured dots) and then let the automatic system be automatic. Make sure the snowflake is selected so you have airconditioning, make sure the air recirc is on auto or non-recirc, and put the fan on automatic as well as the temp setting. With that done, I have always found that fully automatic works great. I think that there are just too many manual settings that get in the way of it being automatic.

Good luck with it.
