Another little known fact is that the higher the setting on your blower, the
longer length of time the compressor will be enagaged.
The thermostat which controls the compressor to engage or disengage
depending on the cabin temp would be warmer, because more of the cabin
(warm) air will be blown its way and the evaporator wouldn't be as cold. The
thermostat will then keep the compressor engaged longer to attain the same
'coldness' as when you set the blower to 1 or 2.
