Hi

Is it normal for the two centre and rear vents to be blowing a lot cooler than the others when in auto mode.
I set the dual climate to 22 degree all other vents blow warm but the centre and rear blow colder.
I have searched for ideas and people say that I should set the vent control to the up down arrow and middle mode?. Is that what you usually have the air con set at? If I did this would the system still regulate the temperature automatically and slow the fans down when at temperature.
Also is there a fix for wind noise through the drivers door on the motorway?
Car is a s line avant 2010
Thanks hope someone can help
