Blower Motor: Description and Operation
GF83.10-P-2051GZK Blower Regulator, Component Description
GF83.10-P-2051GZK Blower Regulator, Component Description
- with CODE (581) Comfort automatic air conditioning
Component Identification
Location
The blower regulator is located on the right below the glove compartment and is attached directly to the blower motor (A32m1).
Task
For exchanging data via the local interconnect network (LIN), the blower regulator is connected to the comfort AAC [KLA] control and operating unit
(N22/7).
The blower regulator regulates the blower motor's voltage supply depending on the particular blower stage set at the comfort AAC [KLA] control and
operating unit.
Function
The comfort AAC [KLA] control and operating unit relays a control voltage of 0 to 100 % to the blower regulator. This then regulates the operating
voltage for the blower motor depending on the control voltage applied from 0 to 100 %. This facilitates control of the blower motor speed from 0 - 100
%.
The blower motor regulator (operating voltage) is influenced by the following factors:
^
Blower output setting (AUTO/manual)
^
AC OFF (ON/OFF)
^
Mode status (heating, cooling)
^
Sun intensity, direction of solar radiation
^
Coolant temperature
^
Vehicle speed
^
Window, sliding roof, tilting roof positions
^
Ambient temperature
^
Air humidity (dew point)
^
Pollutant concentration
^
Fresh air/air recirculation flap actuator motor
^
Flap positions (air distribution)
^
Residual engine heat utilization function, stationary ventilation function
