SYSTEM DESCRIPTION
• The manual air conditioning system is c ontrolled by a sequence of functions from the front air control, BCM,
ECM, and IPDM E/R.
• The fan speed of the front blower motor is changed by t he combination of the fan control dial (fan switch)
operation and blower resistor control.

INSUFFICIENT COOLING
INSUFFICIENT COOLING
DescriptionINFOID:0000000012430750
Symptom
• Insufficient cooling
• No cool air comes out. (Air flow volume is normal.)
Diagnosis ProcedureINFOID:0000000012430751
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.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Check compressor operation. Refer to HAC-50, "
Diagnosis Procedure".
2.CHECK DRIVE BELT
Check tension of drive belt. Refer to EM-17, "
Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Adjust or replace drive belt depending on the inspection results.
3.CHECK REFRIGERANT CYCLE PRESSURE
Connect the recovery/recycling recharging equipment to the vehicle and perform the pressure inspection
using gauge. Refer to HA-15, "
Symptom Table".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace parts depending on the inspection results.
4.CHECK AIR LEAKAGE FROM EACH DUCT
Check duct and nozzle, etc. of t he air conditioner system for 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.

DescriptionINFOID:0000000012430752
Symptom
• Insufficient heating
• No warm air comes out. (Air flow volume is normal.)
Diagnosis ProcedureINFOID:0000000012430753
NOTE:
Perform self-diagnosis with CONSULT before performing sy mptom 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-8, "
Inspection".
2. Check radiator cap. Refer to CO-12, "
RADIATOR CAP : Inspection".
3. Check water flow sounds of the engine coolant. Refer to CO-9, "
Refilling".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Refill engine coolant and repair or replace the 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 outle t side is slightly lower than/almost equal to the inlet
side.
CAUTION:
Always perform the temperature inspection in a sh ort 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-35, "
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 inst allation and air mix door operation.
NO >> Repair or replace parts depending on the inspection results.
