DTC 37	Passenger-side front air mix actuator (potentiometer) (present)
POSSIBLE CAUSE	•  Passenger-side front air mix actuator malfunction •  Open circuit between passenger-side front air mix actuator and front climate control unit •  Short circuit between passenger-side front air mix actuator (terminal E) and front climate control unit (terminal 2G: 16-pin)

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	•  Inspect passenger-side front air mix actuator. (See FRONT AIR MIX ACTUATOR INSPECTION.) •  Is it okay?	Yes	Go to the next step.
		No	Replace passenger-side front air mix actuator. (See FRONT AIR MIX ACTUATOR REMOVAL/INSTALLATION.)
2	•  Disconnect driver side front air mix actuator connector. •  Disconnect front airflow mode actuator connector. •  Disconnect rear air mix actuator connector. •  Disconnect rear airflow mode actuator connector. •  Disconnect ambient temperature sensor connector. •  Disconnect cabin temperature sensor connector. •  Disconnect front and rear evaporator temperature sensor connector. •  Is resistance between terminals 2G and 2P of front climate control unit connector (16-pin) more than 840 ohms?	Yes	Go to the next step.
		No	Repair wiring harness. (Short circuit)
3	•  Disconnect front climate control unit connector (16-pin). •  Is resistance between terminals 2B and 2P of front climate control unit connector (16-pin) less than 7.8 kilohms?	Yes	Go to the next step.
		No	Repair wiring harness. (Open circuit)
4	•  Is resistance between terminals 2B and 2G of front climate control unit connector (16-pin) less than 6.24 kilohms?	Yes	Inspect the connection of the front climate control unit connector.
		No	Repair wiring harness. (Open circuit)
