20. HEATER FAN/ AIR-CONDITIONING SYSTEM
A voltage is applied to the heater fan switch
(C588) through the heater fan fuse (E031).
Depending on the position of this switch, the fan
will start operating.
The switch has five (5) positions:
Off:
Heater fan (B015) off.
Position 1:
Fan at lowest speed setting
(wire 4650), supply of heater
fan (B015) through three (3)
resistors.
Position 2:
Fan at somewhat higher
speed setting (wire 4651),
supply of heater fan (B015)
through two (2) resistors.
Position 3:
Heater fan in next to highest
speed setting (wire 4652),
supply of heater fan (B015)
through one (1) resistor.
Position 4:
Heater fan in highest speed
setting (wire 4653), relay
G065 now activated. This
relay connects the supply
(wire 1201) to wire 4654 and
the heater fan. The relay is
only activated in position 4 (full
supply voltage of heater fan
B015).
AIR-CONDITIONING SYSTEM
SHORT DESCRIPTION OF THE
RECIRCULATION VALVE
If switch C802 (air-conditioning recirculation
valve) is activated, a voltage is applied to point 1
of relays G257 and G258. As a result, pin 2 of
recirculation-valve motor B252 is connected to
earth and simultaneously pin 1 of B252 is
connected to the positive voltage. This will
activate motor B252 and close the recirculation
valve.
If C802 is not activated, no voltage is applied to
both relays G257 and G258. As a result, the
direction of flow of the current through motor
B252 is reversed and the recirculation valve will
open.

SHORT DESCRIPTION OF THE
AIR-CONDITIONING SYSTEM
When the air-conditioning system is engaged
with switch C760, a voltage is applied to relay
G279 through wire 4655 and a voltage to relay
G267 through switch E508 (air-conditioning
compressor temperature switch), E509
(air-conditioning high/low pressure operating
switch) and wire 4657.
As a result, the heater fan (B015) will start
operating in position 1 and the air-conditioning is
activated.
VARIANTS
Location
33 A round 4-pin black connector is attached to
the wiring harness coming from B043
(air-conditioning compressor). This
connector is not provided with a connector
number and is installed at the front (upper
centre) of the engine block.
