ELECTRICAL TROUBLESHOOTING MANUA L
Condenser Fan Operation (Diesel)
The Condenser Fan Motors (M113, M121) on
vehicles equipped with diesel engines operate
when any one of the following conditions occur:
1. Coolant temperature exceeds 100
C (212
F).
2. The A/C is operating.
Condenser Fan with High Coolant Temperature
Operation (Diesel)
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 relays coil.
When the relay is energized, voltage from fuse F3
is applied to the Condenser Fan Motors (M113,
M121) through the relays contacts.
Fan Operation with A/C (Diesel)
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
Fan Speed Switch (X179) 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).

3. Check Fuses F3, and F7 in the Engine
Compartment Fuse Box (P125).
4. Check Fuse F18 in the Fascia Fuse Box.
5. If the Front Blower Motor (M101) does not
operate normally, refer to Blower Controls,
Section K1.

 
1. If the Condenser Fans do not turn on when the
A/C is turned on, do Test A for Petrol Engines
or Test B, the Condenser Fan Relay (K109)
test, for Diesel Engines.
2. If only one of the Condenser Fans operates, do
Test E, the Condenser Fan Motor (M113,
M121) test.
3. If the Condenser Fans do not turn on when
coolant temperature exceeds 100
C (212
F),
do Test F, the Temperature Switch (X113) test.
4. On Petrol Engines, if the Condenser Fans do
not stay on after the ignition has been turned
off, fuel temperature exceeds 70
C and
coolant temperature exceeds 110
C, do Test
G, the Fan Control Module (Z118) test.
