    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 100C (212F).
    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 100C (212F), 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 100C (212F),
    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 70C and
    coolant temperature exceeds 110C, do Test
    G, the Fan Control Module (Z118) test.
