SYMPTOM TROUBLESHOOTING

Troubleshooting item	Description
Amount of air blown from vents does not change (See AMOUNT OF AIR BLOWN FROM VENTS DOES NOT CHANGE .)	Blower motor does not operate even if airflow volume control switch is operated (no airflow from vent). Blower motor operation does not change even if airflow volume control switch is operated (airflow volume from vent does not change).
Insufficient air (or no air) blown from vents (See INSUFFICIENT AIR (OR NO AIR) BLOWN FROM VENTS .)	Insufficient airflow from vent or duct No airflow from vent or duct Airflow mode does not change
Air intake mode does not change (See 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.
No temperature control with climate control unit (See NO TEMPERATURE CONTROL WITH CLIMATE CONTROL UNIT .)	Temperature does not change when operating temperature control switch.
Windshield fogged (See 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.
Air from vents not cold enough (See 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
Switch operation does not respond (See SWITCH OPERATION DOES NOT RESPOND .)	Specific switch operation of climate control unit does not respond.
No cool air (See NO COOL AIR .)	Cold air does not come out even if the temperature is set to MAX COLD. Magnetic clutch does not work.
Dual A/C control does not operate (See DUAL A/C CONTROL DOES NOT OPERATE .)	Driver or passenger side temperature control dial does not operate individually.
Noise while operating A/C system (See 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
Climate control unit does not store information (See CLIMATE CONTROL UNIT DOES NOT STORE INFORMATION .)	When ignition is switched ON (engine off or on), climate control unit activated with set temperature at [22.0 while in AUTO Past malfunction code is not stored in climate control unit.
No warm airflow from vent (See NO WARM AIRFLOW FROM VENT .)	No warm airflow even if airflow temperature setting is MAX HOT.
A/C does not work sufficiently (See A/C DOES NOT WORK SUFFICIENTLY .)	A/C compressor magnetic clutch does not engage when A/C switch is turned on. Compressor valve inoperative
A/C is always on or A/C compressor runs continuously (See A/C IS ALWAYS ON OR A/C COMPRESSOR RUNS CONTINUOUSLY .)	A/C compressor magnetic clutch does not disengage.
Ambient temperature displayed in instrument cluster is extremely lower than actual temperature (See AMBIENT TEMPERATURE DISPLAYED IN INSTRUMENT CLUSTER IS EXTREMELY LOWER THAN ACTUAL TEMPERATURE .)	The ambient temperature displayed in the instrument cluster differs considerably from the actual temperature.
