I've read the user manual and still have a few questions about the Air Con control in my E39. I know the seperate temp setting controls the driver's side and passenger's side individually, but I would expect the air temp will also change on the appropriate door's air vent outlet.
For example, if I change the temp to 25c on the driver's side, only the driver's side air vent at the centre will change temp, not the air vent on the driver's door. Or there is something wrong with my a/c ?
Since you can change the temp using the indivudal temp settings, then what is the main use for the temp dial in the middle? It seems overrides the individual temp setting ?
In the manual it mentioned something about Draft Free ventilation, exactly what is meant by Draft Free ?
Sorry for asking so many questions ...

Torque thanks bud for the reminder and I’ll be reviewing with you the basics of climate control system setting to clarify the following:
1. We know unlimited heat can be achieved at setting the temp at 90 while 60 gets full cool Air…silly I know!
2. Auto button: controls the regulation of the interior temp. Automatically……nothing new here either but this happens through dash, door, and rear outputs.
3. Selecting any other choice (floor/dash/windshield buttons) will override the automatic setting…green light goes out!
4. Plus/minus: control air flow but remember it is constant when the Auto button is selected until a preset interior temp is reached….interior temp sensors feed back mechanism.
5. Press the minus after the last bar on the display will turn both heating/Ac off….simple enough too.
6. Recirculation button with 2 green little lights: when the right side green light is on, no outside air is allowed into the interior i.e getting stuck at NYC Lincoln Tunnel …too much fumes…….left side light on? Your system switches between the outside world and circulation….like being out of the tunnel.
7. DRAFT-FREE VENTILATION:
To me these are too big of words to describe a simple mechanism especially if we know what they mean by driving a car under draft-free conditions; to do so all what you have to do is:
A. Control the rate of Air Flow- dials to the sides of dash outputs
B. Control the direction of Air Flow-fins in the output itself
C. Control/trim/adjust, if you wish the intensity of either the hot and/or the cold air; this is simply done by the in dash middle rotary (dial located between the two dash outputs; blue gets the cold air colder and when turned into red makes the hot air hotter; now you think of in between settings) again for this one think trimming/intensity. A good example is when you turn it to the red while the AC is on 60 or conversely try to turn it to blue with temp at 90. TRY IT
I hope this LONG reply clarifies some issues
