GENERAL DESCRIPTION For the heater and air conditioning system, the heater and cooling units are
combined in a single unit, which, with the a mode film damper and flow rate control
valve in the heater unit, reduces ventilation resistance, increases fan power, and
decreases noise. AUTOMATIC AIR CONDITIONING GENERAL DESCRIPTION

SAFETY PRECAUTIONS Because R-134a refrigerant is a hydro fluorocarbon (HFC) which contains
hydrogen atoms in place of chlorine atoms, it will not cause damage to the ozone
layer.
Ozone filters out harmful radiation from the sun. To assist in protecting the ozone
layer, Mitsubishi Motors Corporation recommends an R-134a refrigerant recycling
device.
Refrigerant R-134a is transparent and colorless in both the liquid and vapor state.
Since it has a boiling point of -29.8°C (-21.64°F) at atmospheric pressure, it will be
a vapor at all normal temperatures and pressures. The vapor is heavier than air, non-
flammable, and no
n-ex
plosive. The followin
g precautions must be observed when

WARNING:Wear safety goggles and gloves when servicing the

When metering R-134a into the refrigeration system, keep the supply tank or cans
in an upright position. If the refrigerant container is on its side or upside down,
liquid refrigerant will enter the system and damage the compressor.
Refrigerant will tarnish bright metal and chrome surfaces, and in combination with
moisture can severely corrode all metal surfaces. OPERATION CONDENSER FAN AND RADIATOR FAN CONTROL
For the operation of each fan, refer to
SYMPTOM PROCEDURES
.
COMPRESSOR CONTROL WHEN OPERATING THE AIR CONDITIONING SWITCH
The air thermo sensor, which senses the temperature of the air flowing out of
the evaporator, deactivates the compressor at 3°C (37.4°F) or below. The dual pressure switch turns OFF when the refrigerant pressure becomes
excessively high or low, thus protecting the compressor circuit. When the air thermo sensor is activated, and the ignition switch, blower switch,
and air conditioning switch are ON, the A/C compressor clutch relay is
energized.
WHEN OPERATING THE MODE SELECTION DIAL
The air conditioning will work when the mode selection dial is set to the
"Defroster" or "Defroster/foot" position or the temperature control dial is set to
the "MAX A/C" position. In other dial positions, when the air conditioning
switch is turned on, the air conditioning will work.

AUTO A/C DIAGNOSIS INTRODUCTION After air is taken in through the damper, it is fed to the evaporator by the blower fan
and motor and cooled. The air cooled by the air mix damper is mixed appropriately
with the warmed air to achieve a comfortable temperature. If the A/C does not
operate or the cooled air is not discharged, the system components or relay may be
faulty. AUTOMATIC AIR CONDITIONING TROUBLESHOOTING STRATEGY Use these steps to plan your diagnostic strategy. If you follow them carefully, you
will be sure that you have exhausted most of the possible ways to find a heater, air
conditioning and ventilation fault.
1. Gather information from the customer.
2. Verify that the condition described by the customer exists.
3. Find the malfunction by following
SYMPTOM CHART
.
4. Verify malfunction is eliminated.
