2007 KIA CARNIVAL Workshop Manual

Rear Blower Unit

2007 > 2.7L V6 GASOLINE >
INSPECTION
1.Connect the battery voltage and check the blower motor rotation.
2.If the blower motor voltage is not operated well, substitute with a known- good blower motor and check for proper
operation.
3. If the problem is corrected, replace the blower motor.
REPLACEMENT
1.Disconnect the negative ( - ) battery terminal.
2. Disconnect the connector (A) of the blower motor.
3. Remove the blower motor (A) after loosening the mounting screws.
4.Installation is the reverse order of removal.

Rear Temperature Control Actuator

2007 > 2.7L V6 GASOLINE >
DESCRIPTION
1.Heater unit includes mode control actuator and temperature control actuator.
2. Temperature control actuator is located at the heater unit. It regulates the temperature by the procedure as follows.
Signal from control unit adjusts position of temperature door by operating temperature switch and then temperature
will be regulated by the hot/cold air ratio decided by position of temperature door.

2007 > 2.7L V6 GASOLINE >
INSPECTION
1.Ignition "OFF".
2. Disconnect the connector of temperature control actuator.
3. Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 1 and
grounding terminal 2.
Verify that the temperature control actuator operates to the cool position when connecting in the reverse.
4.Check the voltage between terminals 3 and 4.
Specification
Door position Voltage (3- 4)Error detecting
Max. cooling 0.4 ± 0.15VLow voltage : 0.1V or less
Max. heating 4.6 ± 0.15VHigh voltage : 4.9V or more
* It will feedback current position of actuator to controls.
5. If the measured voltage is not specification, substitute with a known- good temperature control actuator and check
for proper operation.
6. If the problem is corrected, replace the temperature control actuator.
REPLACEMENT
1.Disconnect the negative ( - ) battery terminal.
2. Remove the luggage side trim (Refer to BD - ).
3. Remove the rear heater unit (Refer to HA - ).
4. Disconnect the temperature control actuator connector after removing the air duct.
5. Loosen the mounting screw and then remove the temperature control actuator (A).
6.Installation is the reverse order of removal.

Rear Mode Control Actuator

2007 > 2.7L V6 GASOLINE >
INSPECTION
1.Ignition "OFF".
2. Disconnect the connector of mode control actuator.
3. Verify that the mode control actuator operates to the defrost mode when connecting 12V to the terminal 1 and
grounding terminal 2.
4. Verify that the mode control actuator operates to the vent mode when connecting in the reverse.
5.Check the voltage between terminals 3 and 4.
Door position Voltage (3- 4)Error detecting
Vent 0.4 ± 0.15VLow voltage :0.1V or less
Defrost 4.6 ± 0.15VHigh voltage :4.9V or more
REPLACEMENT
1.Disconnect the negative ( - ) battery terminal.
2. Remove the rear heater unit.
3. Disconnect the mode control actuator connector (A).
4. Loosen the mounting screws and then remove the mode control actuator (B).
5.Installation is the reverse order of removal.
