1A-2 HEATER AND VENTILATION
GENERAL DESCRIPTION
The heater, an in and out air selectable-type hot water heater, is so constructed that it is possible to assure an
agreeable ventilation at all times by providing the ventilator air outlets at the center and both sides (right and left)
of the instrument panel, the hot air outlet at a place close to the feet of front passengers, and the defroster air outlets
at places, right and left, along the windshield glass.
The heater and ventilation consist of following parts.

HEATER AND VENTILATION 1A-3
BODY VENTILATION
The body ventilation system of this vehicle has a fresh air intake located at the cowl top panel. When fresh air intake
control lever is at FRESH AIR position, ventilating air is drawn into the interior from the cowl center garnish and
drawn out from the ventilator outlet provided at each side body outer panel (both right and left side).

QUICKLY CHECKING OF REFRIGERANT
CHARGE (IF EQUIPPED WITH SIGHT GLASS)
CHARGE OF REFRIGERANT
The following procedure can be used for quickly checking whether
the A / C system has a proper charge of refrigerant or not.
Run engine at fast idle, and operate A / C at its max. cooling capacity
for a few minutes. Then, look at the sight glass (1) on receiver / dryer
(2) and compare what is observed with the symptoms listed in
ªCHECKING REFRIGERANT CHARGEº table given below.
CHECKING REFRIGERANT CHARGE
CONDITIONPOSSIBLE CAUSESCORRECTION
Bubbles observed in sight glassInsufficient charge of refrigerant in
systemCheck system for leaks with a leak
tester.
No bubbles observed in sight glassNo charge or proper or too much
charge of refrigerant in systemRefer to the following item.
No temperature difference
between compressor inlet and
outletEmpty or nearly empty systemRecovery, evacuate and charge
system and then check it for leaks
with a leak tester.
Noticeable temperature difference
between compressor inlet and
outletProper or too much charge of
refrigerant in systemRefer to the following item.
When A / C is turned OFF,
refrigerant in sight glass clears
immediately and remains clearToo much charge of refrigerant in
systemDischarge excess charge of
refrigerant to adjust it to a specified
charge.
When A / C is turned OFF,
refrigerant in sight glass once
produces bubbles and then clearsProper charge of refrigerant in
systemNo correction needed because
charge of refrigerant is normal.

1B-12 AIR CONDITIONING (OPTIONAL)
PERFORMANCE DIAGNOSIS
1) Confirm that vehicle and environmental conditions are as fol-
lows.
Vehicle is not exposed to direct sun.
Ambient temperature is within 15C ± 35C (59F ± 95F).
2) Make sure that high pressure valve (1) and low pressure valve
(2) of manifold gauge are firmly closed.
3) Connect high pressure charging hose (3) to high pressure ser-
vice valve (5) on vehicle, and connect low pressure charging
hose (4) to low pressure service valve (6) on vehicle.
4) Bleed the air in charging hoses (3), (4) by loosening their respec-
tive nuts on manifold gauge, utilizing the refrigerant pressure.
When a hiss is heard, immediately tighten nut.
CAUTION:
Do not interchange high and low pressure charging
hoses by mistake.
5) Warm up engine to normal operating temperature (engine cool-
ant temperature at 80 ± 90C (176 ± 194F)) and keep it at spe-
cified idle speed. (Radiator cooling fan should not be working
when checking pressure and temperature.)
6) Turn A / C switch ON, and set blower switch at ªHIº (4th position),
temperature control knob at ªCOOLº, air outlet control knob at
ªFACEº, fresh / circulation control knob at ªCIRCULATIONº.
(Confirm that A / C compressor and condenser fan are working.)
7) Keep all windows, doors and engine food open.

15 ± 35C (59F ± 95F)

8) With about 20 mm (0.8 in.) of dry bulb thermometer (1) inserted
into center duct air outlet and another one set near evaporator
air inlet, read temperature indicated on each thermometer.

9) Check for each pressure of low side and high side if it is within
shaded range of graph.
If each gauge reading is out of specified pressure, correct de-
fective part referring to following Test Diagnosis table.
Example:
Gauges should read as follows when ambient
temperature is 30C.
Pressure on high pressure
gauge (HI):1400 ± 1750 kPa
14.0 ± 17.5 kg / cm
2
Pressure on high pressure
gauge (LO):230 ± 350 kPa
2.3 ± 3.5 kg / cm
2
NOTE:
Pressure registered on gauge varies with ambient temper-
ature. Therefore, use left graphs when determining if pres-
sures are normal or not.
10) Check inlet port temperature-to-outlet port temperature rela-
tionship using graph.
For example, if evaporator inlet port temperature is 25C
(77F) and center duct air outlet temperature is 8C (46.4F),
their crossing point is within acceptable range as shown in
graph.
11) If crossing point is out of acceptable range, diagnose trouble
referring to following Performance Diagnosis table.
