Introduction HVAC Blower and Fan Systems
A breath of fresh air
Air is one of the prerequisites for life – and essential on
any type of car. As well as providing cooling for the
engine, air is used to ventilate the passenger compart-
ment, demist the windows and regulate the internal
temperature. In order to maintain these crucial functions,
VDO HVAC blower and fan systems are designed for the
optimum combination of performance and reliability.
Since the majority of fan systems and radiators are
relatively exposed within the engine compartment, they
are particularly prone to failure or faults caused by dirt or
debris from the road. Frontal impact can also result in
damage to the radiator and fan. Furthermore, as com-
ponents age they become increasingly susceptible to
cracks and corrosion in vulnerable areas such as moun-
ting points and welds. When a failure occurs, it can have a
direct impact on the operation of the engine and
air-conditioning system, with serious consequences in
terms of both safety and comfort. Damage to the radiator
can have a knock-on effect on other components in the
cooling and air-conditioning systems. The cumulative
damage can be extremely expensive, particularly in the
6
event of complete engine failure.
VDO genuine brand replacement parts are specifically
designed to ensure maximum quality, optimum perfor-
mance and ease of installation. The current range of
HVAC blower and fan systems includes the following
component groups:
– Cooling Modules
– Cooling Motors
– Cooling Fans
– Blower Modules
– Blower Motors
– Blower Resistors
