<E36> Climate Control

This is good but!!!  I must be doing somehting wrong because my climate control 
does not seem to work. My fan runs all the time no matter what the setting until 
"I" manually turn it down. Has anybody seen this?

Thanks,

Upon starting the car, if the digital climate control detects that the 
temperature you have set (showing on the climate control) is very different 
from the temperature of the cabin, it will try to heat or aircondition 
(assuming you left it on) to get the temperature to the level you desire. In 
order to do this, it will increase the fan blowing speed for a while, until the 
new temperature has been reached, at which point it will reduce it again by 
itself to whatever level YOU had set before.

Another interesting point is that the fan control switch seems to operate a few 
"notches" beyond the max setting on the display.  I noticed that if I click it 
up after it is at its max display level, it will still increase for about 4 
steps.  This is proven by the fact that when I press the down settings, it 
takes four clicks before the display actually starts decreasing.  The blower 
output is not much greater, but I can sense an increase in airflow when beyond 
the max display position.  Perhaps this speed is used when you put the defogger 
on...
