Condenser Fan Operation (300Tdi)
The Condenser Fan Motors (M113, M121) on
vehicles equipped with diesel engines operate
when any one of the following conditions occur:
1.
2.
Coolant temperature exceeds 100_C (212_F).
The A/C is operating.
Condenser Fan with High Coolant Temperature
Operation (300Tdi)
When the Ignition Switch (X134) is in position II,
battery voltage is applied to the Ignition Load Relay
(K127). The relay is energized, applying battery
voltage to the Condenser Fan Relay_ (K109)._ If the
coolant temperature exceeds 100 C (212 F), the
Condenser Fan Coolant Temperature Switch
(X113) closes and energizes the Condenser Fan
Relay (K109) by applying ground to the relay’s coil.
When the relay is energized, voltage from fuse F3
is applied to the Condenser Fan Motors (M113,
M121) through the relay’s contacts.
Fan Operation with A/C (300Tdi)
With the Igntion Switch (X134) in position II, battery
voltage is applied to the Ignition Load Relay
(K127). The relay is energized, applying battery
voltage to the Condenser Fan Relay (K109) when
the Front A/C Switch (X225) is turned on and the
Front Fan Speed Switch (X247) is turned to
positions I, II, II, or IV, ground is applied to terminal
86
of the Condenser Fan Relay (K109). The relay
energizes, applying battery voltage from fuse F3 to
the Condenser Fan Motors (M113, M121).
