In-vehicle temperature sensor
E97731
The interior temperature sensor measures the
temperature in the passenger compartment and
thereby also helps to control the pre-selected
interior temperature. This is an NTC resistor.
In order to achieve optimum measurement values,
an integrated blower draws air from the interior into
the in-vehicle temperature sensor.
Ambient temperature sensor
E98860
The outside-temperature sensor measures the
ambient temperature outside the vehicle. The
resistance, and so the voltage drop at the sensor,
alter depending on the outside-air temperature.
This is an NTC resistor.
Blower motor
E98855
On vehicles with electronic automatic temperature
control (EATC), a blower motor with brushes is
used.
Blower control module - vehicles equipped
with automatic temperature control
E97726
On vehicles with electronic automatic temperature
control (EATC) a blower control module is fitted
instead of the conventional blower motor resistor.
This is located in the usual position next to the
blower motor, so that the cooling fins of the module
are cooled by the air flow.
The climate control module regulates the blower
control module via a PWM signal, which in turn
regulates the voltage at the blower motor to
between 3 V and 12.8 V, in an infinitely variable
manner.
The blower control module is fitted with a
temperature monitor which continuously monitors
the internal temperature of the module. If the
temperature rises above 105°C, the blower motor
is switched off until the temperature in the module
falls to below 100°C.
If the current rises above the value of 26 A ± 3 A
defined in the blower control module (e.g. high
