Does your dual zone climate control over compensate for sunlight?

• On hot days, I need to set the control to 25 degrees so it doesn't continue to blast cold air in my face. Vice versa on cold days.
• When entering a very hot cabin, it is far too conservative in blasting the cabin with cold air. The fan is never set to maximum, so I do it manually.
• If the unit is set to Off, then nothing should come out of the vent. I always get the climate du jour filtering through the vents when I do this. But I can't close the vent with the unit off.

Amusingly, one of my complaints is the opposite of yours: I often find that the fan speed is a couple of clicks faster than I'd prefer when I first get into the car on a warm day.

Allowing some amount of outside air into the cabin when the fan's switched off is how every car I've ever owned has behaved, and it seems quite odd that you'd want anything else. I do find that I've had the temperature set slightly lower in winter than in summer, but mainly that's due to often wearing a jumper and possibly a jacket as well when it's cold outside.

Actually... facing the vents away from your face/body may solve alot of the A/C problems people are facing (pardon the pun).
You dont usually sit in a room or office with the A/C blowing on you. The air coming out of the car vents is WAY colder than that temp set on the dial. Mix that with the wind chill of moving air then I can understand why some people could find the climate control erratic. Its trying to cool the entire cabin, not just the person the air is blowing on.

That makes a lot of sense, I'm going to try that next time I drive. On the other hand, on a hot summer's day I usually prefer to have 'as cold as possible' air blowing directly on me, because no car aircon can maintain a sensible cabin temperature with 40-plus-degree sun pelting down.
