Rear Heater - Rear Temperature Control

Actuator

Heating, Ventilation, Air Conditioning

2009 > G 2.7 DOHC >

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.

2009 > G 2.7 DOHC >

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.

Max. cooling

0.4 ± 0.15V

Low voltage : 0.1V or less

Max. heating

4.6 ± 0.15V

High 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.
