Blower, function - GF83.10-P-2102-02I

Function 

The automatic A/C pushbutton control module transfers a control voltage of 0 - 6V to the blower control. This then controls the operating voltage for the blower (0-12 V) depending on the control voltage present. This provides for control of the blower speed from 0 -100 %.

The blower control (operating voltage) is affected by the following factors:

• Blower speed setting (AUTO/manual)
• Control functions (ON/OUT, EC, REST, air distribution)
• Mode (heating/air conditioning)
• Sun intensity
• Coolant temperature
• Vehicle speed
• Position of fresh air/recirculated air flap
• Position of activated charcoal filter flap
• Flap positions
• Number of passengers (via occupied seat recognition feature in front seats)
• Circuit 15 (blower ON), starter running (blower OFF)
