Radiator fan does not run at all,
but condenser fan runs with A/C
ON
Radiator and condenser fan circuit troubleshooting A (see
page 10-22).
Both radiator fan and condenser
fan do not run on low or high
speed with the A/C ON or when
the engine coolant temperature
is above 210°F (99°C)
Check the No. 3 (15A) fuse in the driver’s under-dash
fuse/relay box.
If the fuse is faulty, replace it.
If the fuse is OK, repair the open in the wire between the
No. 3 (15A) fuse in the driver’s under-dash fuse/relay
box and the radiator and condenser fan relays.
Condenser fan runs but radiator
fan does not run when the
engine coolant temperature is
above 199°F (93°C), but both
fans run with the A/C ON
Replace the radiator fan control relay.
Both the radiator fan and
condenser fan do not run at low
speed when the engine coolant
temperature is above 199°F
(93°C), but both fans run with
A/C ON and when the engine
coolant temperature is above
210°F (99°C)
Radiator and condenser fan circuit troubleshooting B (see
page 10-23).
Both radiator and condenser
fans do not run when the
engine coolant temperature is
above 199°F (93°C), but radiator
fan runs with A/C ON
Radiator and condenser fan low speed circuit
troubleshooting (see page 21-27).
Both radiator fan and condenser
fan run with ignition switch ON
(II), with A/C OFF, and when the
engine coolant temperature is
below 199°F (93°C)
Radiator and condenser fan circuit troubleshooting C (see
page 10-24).
Both radiator fan and condenser
fan do not run at high speed
with the A/C ON
Radiator and condenser fan high speed circuit
troubleshooting (see page 21-31).
Both radiator fan speed and
condenser fan speed do not
change from low to high when
the engine coolant temperature
is above 210°F (99°C), but both
fans speed change with A/C ON
Radiator and condenser fan high speed circuit
troubleshooting (see page 10-24).
Condenser fan speed does not
change from low to high with
A/C ON or the when engine
coolant temperature is above
210°F (99°C)
Condenser fan high speed circuit troubleshooting (see
page 21-31).
