TROUBLESHOOTING HINTS1. Neither the radiator fan nor condenser
fan rotate at all.l Check fusible link No. 5
2. Only the condenser fan does not
operate.l Check dedicated fuse No. 8.
3. The radiator fan and condenser fan do
not operate in the low speed mode, but
operate otherwise.(1) The
AK compressor magnet clutch does
not enter the “ON” state.
lCheck whether the output of the auto
compressor control unit is available.
NOTE
For troubleshooting of the air conditioningcontrol unit, refer to GROUP 55.
(2) The A/C compressor magnet clutch enters
the “ON” state.l Check the resistor.
lCheck the radiator fan motor relay (LO)
and condenser fan motor relay (LO).l
Check the therm0 sensor (for radiator
fan).
(3) The radiator fan does not rotate when the
air conditioning switch is turned ON.l Check the radiator fan motor control
relay.4. The radiator fan and condenser fan do
not operate in the high speed mode, but
operate otherwise.l Check the
therm0 sensor (for condenser
fan).l
Check the radiator fan motor relay (HI) and
condenser fan motor relay (HI).Fan Operating Mode
