permitted, the high-pressure switch turns off the
refrigerant compressor.
The compressor on-off cycle is controlled by the
dual pressure switch depending on the pressure
in the refrigerant accumulator. The dual pressure
switch turns the refrigerant compressor off
permanently if the pressure falls below a permitted
value (e.g. if there is a leak).
Component Description
Air conditioning compressor
E100826
The special feature of a compressor with variable
swash plate is that the stroke of the pistons can
be varied by means of the variable swash plate.
The swash plate is mounted on a slide rail in the
axial direction.
The piston stroke and thus the delivery rate are
determined by means of the variable obliqueness
of the swash plate.
The obliqueness of the swash plate is dependent
upon the chamber pressure and thus on the
pressure conditions at the top and bottom of the
piston. This is supported by springs in front of and
behind the swash plate.
The chamber pressure is determined by the high
and low pressure applied to the control valve and
by a calibrated orifice bore. If the low pressure is
relatively high, the control valve is opened and the
chamber pressure is reduced.
If the low pressure is relatively low, the control
valve is closed and the chamber pressure is
increased. The force due to the chamber pressure
exerted on the piston bottom, is higher than the
sum of the force due to the low pressure on the
piston top and the spring force.
Pollen filter
E97720
The fresh air flowing into the vehicle through the
air inlet housing passes through a pollen filter which
is located on the left-hand side of the climate
control housing (LHD and RHD) and removes
pollen and dust particles measuring 0.003 mm or
more.
Control assembly, climate control -
vehicles with manual temperature control
E97721
In vehicles with manual temperature control, the
heating and air conditioning are operated using
three rotary switches. The air distribution flaps are
actuated via the air distribution flap/temperature
control flap actuating unit, which is connected via
a rod to the control assembly for the climate
control. The temperature control flap is also
actuated via the air distribution flap/temperature
control flap actuating unit, which is connected via
a cable to the control assembly. In addition, the
operating switch for recirculated air mode and the
on/off switch for the air conditioning are located on
the control assembly.

Control assembly, climate control -
vehicles with automatic temperature
control
E97722
Vehicles with automatic temperature control have
a control assembly with the following button
operated functions:
• Switching the air conditioning system on andoff
• Temperature adjustment for the driver's side/front passenger's side
• Switching the windshield defrost function on and off
• Switching the electronic automatic climate control and the dual mode on and off
• Air distribution
• Blower Control
• Switching off the dual automatic climate control
• Recirculated air control
Control assembly, climate control -
vehicles with DVD navigation system with
a touch screen
E97723
On vehicles with a DVD navigation system with a
touch screen, the control buttons for the automatic
temperature control (climate control) are integrated in this unit. In addition, all heating and air
conditioning functions can be controlled via the
touchscreen. The information exchange takes place
on the mid-speed CAN bus (MS-CAN).
Climate control module - vehicles with DVD
navigation system with a touch screen
E97724
On vehicles with a DVD navigation system with a
touch screen, the climate control module is
provided as a separate component underneath the
DVD navigation unit. It is actuated via control
buttons or via the navigation touch screen.
Sun sensor - vehicles with automatic
temperature control
E97725
For vehicles with automatic temperature control
the sun sensor determines the intensity of the
sunload. The sunload serves as an additional
parameter for determining the blower air
temperature, the air distribution and the blower
speed.

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

dynamic pressure in blower housing during fast
motorway driving), the current flow through the
blower motor is limited by the blower control
module, until a safe value is reached. If this value
cannot be achieved (e.g. blower motor blocked or
partially seized or dynamic pressure in the blower
housing permanently too high), the value is limited
to6A±2A.
Under normal conditions, the blower motor control
returns to the normal state.
