Insufficient air (or no air) blown from vents

•  Insufficient airflow from vent or duct

•  No airflow from vent or duct

•  Front airflow mode does not change

(See INSUFFICIENT AIR (OR NO AIR) BLOWN FROM VENTS [FULL-AUTO AIR CONDITIONER].)

Amount of air blown from vents does not change

•  Front blower motor does not operate even if airflow volume control switch is operated (no airflow from vent)

•  Front blower motor operation does not change even if airflow volume control switch is operated (airflow volume from vent does not change)

(See AMOUNT OF AIR BLOWN FROM VENTS DOES NOT CHANGE [FULL-AUTO AIR CONDITIONER].)

Air intake mode does not change

•  Air intake mode does not change when switching REC/FRESH mode

•  No change in wind noise when airflow volume is set to 3 or more even if REC/FRESH switch is operated

(See AIR INTAKE MODE DOES NOT CHANGE [FULL-AUTO AIR CONDITIONER].)

Switch/dial operation does not respond

•  Specific switch/dial operation of front climate control unit does not respond

(See SWITCH/DIAL OPERATION DOES NOT RESPOND [FULL-AUTO AIR CONDITIONER].)

All switch/dial operation does not respond

•  All switch/dial operation of front climate control unit does not respond

•  Indicator light of front climate control unit does not turn on

(See ALL SWITCH/DIAL OPERATION DOES NOT RESPOND [FULL-AUTO AIR CONDITIONER].)

No temperature control with climate control unit

•  Temperature does not change when operating temperature control dial

•  Malfunction in A/C unit and/or front climate control unit air mix system

•  Malfunction in driver and/or passenger side air mix actuator or related wiring harness

(See NO TEMPERATURE CONTROL WITH CLIMATE CONTROL UNIT [FULL-AUTO AIR CONDITIONER].)

Windshield fogged

•  A/C compressor does not operate while airflow mode is in DEFROSTER or DEF/HEAT modes

•  Air intake mode does not change to FRESH while airflow mode is in DEFROSTER or DEF/HEAT modes

(See WINDSHIELD FOGGED [FULL-AUTO AIR CONDITIONER].)

Air from vents not cold enough

•  Insufficient cooled-airflow even if airflow temperature setting is MAX COLD

•  Excessive time required to cool to set temperature

(See AIR FROM VENTS NOT COLD ENOUGH [FULL-AUTO AIR CONDITIONER].)

No cool air from vent

•  Magnetic clutch does not operate

•  No cool airflow even if airflow temperature setting is MAX COLD

(See NO COOL AIR [FULL-AUTO AIR CONDITIONER].)

Noise while operating A/C system

•  Abnormal noise occurring from near A/C compressor during A/C operation

•  Abnormal noise occurring from near A/C compressor regardless of A/C operation

•  Occasional abnormal noise occurring from near A/C compressor during A/C operation

(See NOISE WHILE OPERATING A/C SYSTEM [FULL-AUTO AIR CONDITIONER].)

Dual A/C control does not operate

•  Driver or passenger side temperature control dial does not operate individually

(See DUAL A/C CONTROL DOES NOT OPERATE [FULL-AUTO AIR CONDITIONER].)

Climate control unit does not store information

•  When ignition is switched ON (engine off or on), climate control unit activated with set temperature at 22 °C {72 °F} while in AUTO

•  Past malfunction code is not stored in climate control unit

(See CLIMATE CONTROL UNIT DOES NOT STORE INFORMATION [FULL-AUTO AIR CONDITIONER].)
