Symptom

• Insufficient cooling

• No cool air comes out. (Air flow volume is normal.)

Diagnosis Procedure

INFOID:0000000012200139

NOTE:

Perform self-diagnosis with CONSULT before performing symptom diagnosis. If any malfunction result or DTC

is detected, perform the corresponding diagnosis.

1.

CHECK MAGNET CLUTCH OPERATION

1. Turn ignition switch ON.

2. Turn fan control dial ON.

3. Press A/C switch.

4. Check that A/C indicator turns ON. Check visually and by sound that compressor operates.

5. Press A/C switch again.

6. Check that A/C indicator turns OFF. Check that compressor stops.

INSUFFICIENT HEATING

Description

INFOID:0000000012200140

Symptom

• Insufficient heating

• No warm air comes out. (Air flow volume is normal.)

Diagnosis Procedure

INFOID:0000000012200141

NOTE:

Perform self-diagnosis with CONSULT before performing symptom diagnosis. If any malfunction result or DTC

is detected, perform the corresponding diagnosis.

1.

CHECK COOLING SYSTEM

1. Check engine coolant level and check for leakage. Refer to 

CO-10, "Inspection"

.

2. Check radiator cap. Refer to 

CO-14, "RADIATOR CAP : Inspection"

.

3. Check water flow sounds of the engine coolant. Refer to 

CO-11, "Refilling"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Refill engine coolant and repair or replace parts depending on the inspection results.

2.

CHECK HEATER HOSE

Check installation of heater hose by visually or touching.
Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace parts depending on the inspection results.

3.

CHECK HEATER CORE

1. Check temperature of inlet hose and outlet hose of heater core.

2. Check that inlet side of heater core is hot and the outlet side is slightly lower than/almost equal to the inlet

side.

CAUTION:

Always perform the temperature inspection in a short period of time because the engine coolant

temperature is very hot.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Replace heater core. Refer to 

HA-46, "HEATER CORE : Removal and Installation"

.

4.

CHECK AIR LEAKAGE FROM EACH DUCT

Check duct and nozzle, etc. of air conditioning system for air leakage.
Is the inspection result normal?

YES

>> Check air mix door cable installation and air mix door operation.

NO

>> Repair or replace parts depending on the inspection results.
