DEFECTIVES IN FAN MOTOR CIRCUIT
Fan Motor Does Not Run
Blown fuse
Battery voltage is low
Faulty wiring
Faulty groundChecksActionCheck for short and replace fuse.
Check battery voltage.
Check connectors’ connection.
Do not apply grease. This can cause voltage down.
Remove body painting and completely ground,
Tighten ground bolts and make sure body ground
connection.
Fan Motor Runs in ‘4’position Only (‘3’, ‘2’, ‘1’ : Does Not Run)
Motor Runs With Poor Blowing
Blown resister temperature fuse
Air leakage in parts connectionChecksActionReplace resistor.
Check heater, cooling unit and blower for proper
connection.
Clogged or blocked intake grilleChecksActionClogged or blocked intake grille reduces blowing
capacity.
Frosted Evaporator
Faulty thermo ampChecksActionFrosted evaporator reduces cooling capacity.
Off compressor and maximize blowing capacity

KAA7D310
Fault : intake (recirculation/fresh air) door inoperative
Remove the glove box.
Check No. 24 fuse (15A) in the box.
YesNo
Check that it operates toward each direction after
connecting the battery to the 6C terminal of intake
actuator and ground 6A & 6B to the body.
Wiring side connector
Intake actuator is normal.
YesRepair and replace the intake actuator. No
Check intake actuator linkage and door for
proper operation and repair if necessary.Disconnect 20-pin connector from the airconditioner
control unit.
Check current between the intake actuator (6A, 6B)
and the airconditioner control unit (6,7).
Is there current?
YesRepair open wire between the intake actuator
and the control unit. No
Replace the good control unit and re-check. If no
fault, replace the control panel.
Measure voltage between 6c terminal positive pole
(+) and body (-).
Measured voltage is 12V.
Turn the ignitin switch OFF and disconnect harness
of the intake actuator.
Disconnect 3-pin connector of the intake mode
actuator and turn the ignition switch to ON position.

7D-22 FATC-HAVC
Fault : air flow does not change toward panel side.
Remove the center panel of the instrument panel.
Measure voltage between 8I terminal positive pole
(+) and body (-).
Measured voltage is 12V.Check No. 24 fuse (15A) in the fuse box.
Turn the ignition switch OFF and disconnect harness
of the mode actuator.YesNo
Disconnect 8-pin connector of the mode actuator and
turn the ignition switch to ON position.
Check that it operates toward each directions when
ground is connected to terminal (8J, 8H, 8F, 8D, 8B)
of the mode actuator alternatively.
Mode actuator is normal.
YesRepair and replace the mode actuator. No
Check the intake actuator linkage and door
for proper operation and repair if necessary.Disconnect 20-pin connector from the airconditioner
control unit.
Check current between the mode actuator (8J, 8H,
8F, 8D, 8B) and the airconditioner control unit (11,
12, 13, 14, 15).
Is there current?
YesRepair open wire between the mode actuator
and the control unit. No
Replace the good control unit and re-check. If no
fault, replace the control panel.
