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 4 and grounding terminal 3 Verify that the temperature control actuator operates to the cool position when connecting in the reverse.
1. - 2. - 3. Cool position 4. Hot position | 5. Sensor (+5V) 6. Feedback signal 7. Sensor ground
4. | Check the voltage between terminals 6 and 7. Specification
Door position | Voltage (6-7) | Error detecting
Max. cooling | 0.45 ± 0.15V | Low voltage : 0.1V or less
Max. heating | 4.55 ± 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 heater & blower unit. (Refer to HA group - "Heater Unit")
3. | Remove the heater unit from the blower unit. (Refer to HA group - "Heater Unit")
4. | Loosen the mounting screws and then remove the temperature control actuator (A).
