4. Press temperature control switch as desired. Temperature will change at a rate of 1°C each time a switch
is pressed.
When battery cable is disconnected or battery voltage is 9.0V or less, trimmer operation is cancelled. Set
temperature returns to the initial condition, i.e. 0°C.

Component Function CheckINFOID:0000000001547452
SYMPTOM: Insufficient cooling
INSPECTION FLOW
1.CONFIRM SYMPTOM BY PERFORMING OPERATIONAL CHECK - TEMPERATURE DECREASE
1. Press the AUTO switch.
2. Turn temperature control dial (driver) counterclockwise until 16° C (60° F) is displayed.
3. Check for cold air at discharge air outlets.
Can the symptom be duplicated?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK FOR ANY SYMPTOMS
Perform a complete operational check for any symptoms. Refer to HAC-87, "
Operational Check".
Does another symptom exist?
YES >> Refer to HAC-184, "SymptomMatrixChart".
NO >> System OK.
3.CHECK FOR SERVICE BULLETINS
Check for any service bulletins.
>> GO TO 3.
4.PERFORM SELF-DIAGNOSIS
Perform self-diagnosis Refer to HAC-98, "
Front Air Control Self-Diagnosis".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Refer to HAC-104, "
A/C System Self-Diagnosis Code Chart".
5.CHECK DRIVE BELTS
Check compressor belt tension. Refer to XX-XX, "*****"
.
Is the inspection result normal?
OK >> GO TO 6.
NG >> Adjust or replace compressor belt. Refer to XX-XX, "*****"
.
6.CHECK AIR MIX DOOR OPERATION
Check and verify air mix door mechanism for smooth operation. Refer to XX-XX, "*****"
Does air mix door operate correctly?
YES >> GO TO 7.
NO >> Check air mix door motor circuit. Refer to HAC-112, "

Whenever system’s high and/or low side pressure(s) is/are unusual, diagnose using a manifold gauge. The
marker above the gauge scale in the following tables indicates the standard (usual) pressure range. Since the
standard (usual) pressure, however, differs from vehicle to vehicle, refer to above table (Ambient air tempera-
ture-to-operating pressure table).
Both High- and Low-pressure Sides are Too High
High-pressure Side is Too High and Low-pressure Side is Too Low
High-pressure Side is Too Low and Low-pressure Side is Too High
Gauge indication Refrigerant cycle Probable cause Corrective action
Both high- and low-pressure
sides are too high.Pressure is reduced soon af-
ter water is splashed on con-
denser.Excessive refrigerant charge in refrig-
eration cycle.Reduce refrigerant until
specified pressure is ob-
tained.
Air suction by cooling fan is in-
sufficient.Insufficient condenser cooling perfor-
mance.
↓
1. Condenser fins are clogged.
2. Improper fan rotation of cooling
fan. Clean condenser.
 Check and repair cooling
fan if necessary.
 Low-pressure pipe is not
cold.
 When compressor is
stopped high-pressure val-
ue quickly drops by approx-
imately 196 kPa (1.96 bar, 2
kg/cm
2, 28 psi). It then de-
creases gradually thereaf-
ter.Poor heat exchange in condenser
(After compressor operation stops,
high-pressure decreases too slowly.).
↓
Air in refrigeration cycle.Evacuate repeatedly and
recharge system.
Engine tends to overheat. Engine cooling systems malfunction.Check and repair each en-
gine cooling system.
 An area of the low-pressure
pipe is colder than areas
near the evaporator outlet.
 Plates are sometimes cov-
ered with frost. Excessive liquid refrigerant on low-
pressure side.
 Excessive refrigerant discharge
flow.
 Expansion valve is open a little
compared with the specification.
↓
Improper expansion valve adjust-
ment.Replace expansion valve.

High-pressure side is too high
and low-pressure side is too low.
Upper side of condenser and
high-pressure side are hot,
however, liquid tank is not so
hot.High-pressure tube or parts located
between compressor and condenser
are clogged or crushed. Check and repair or re-
place malfunctioning
parts.
 Check oil for contami-
nation.
