REAR AIR STREAM TEMPERATURE SENSOR, LOCATION/TASK/FUNCTION - GF83.57-P-2118GI
MODEL 163 as of 1.9.01 with CODE (580a) Automatic air conditioning

Front footwell vent air
temperature sensor,
locationThe front footwell vent air temperature sensor (B10/25) is located to the left of
the automatic air conditioning box below the instrument panel.

Front footwell vent air
temperature sensor,
taskThe front footwell vent air temperature sensor (B10/25) records the temperature
of the air flowing in the front footwell and sends it to the AAC push-button
control module (N22).


Front footwell vent air
temperature sensor,
functionThe vent air's recorded temperature value is compared by the AAC push-button
control module (N22) with the setting in the temperature selector wheel and
authorizes a corresponding adjustment to the blending air flap to be made
depending upon the result.
