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

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

.
4. Verify malfunction is eliminated.

Door Mirror - Endeavor
GENERAL DESCRIPTION REMOTE CONTROLLED MIRROR OPERATION
The mirror glass on the remote controlled mirror moves up/down and left/right
by operating the remote controlled door mirror switch when the ignition switch
is in the "ON" or "ACC" position.
DOOR MIRROR HEATER OPERATION
The defogger relay switch is activated (ON) by turning on the A/C-ECU built-
in defogger switch when the ignition switch is in the "ON" position. When the
defogger relay is turned ON, power is supplied to the defogger and remote
controlled mirror, and the heater of the remote controlled mirror (heated door
mirror) starts operations. The defogger comes with a timer function and will
automatically turn OFF the switch approximately 11 minutes after the defogger
switch is turned ON. The door mirror heater operations are also terminated
along with the defogger, at this time.
HEATED DOOR MIRROR DIAGNOSIS TROUBLESHOOTING STRATEGY Diagnosis should be carried out by the following procedures.
1. Gather the information from the customer.
2. Verify that the condition described by the customer exists.
3. Find the malfunction by the following Symptom Chart.

If both of the door mirror heaters do not operate normally it may be due to a
malfunction in the defogger system. TROUBLESHOOTING HINTS
Malfunction of the defogger system The wiring harness or connectors may have loose, corroded, or damaged
terminals, or terminals pushed back in the connector.
DIAGNOSIS Required Special Tools:
MB991223: Test Harness Set
STEP 1. Check the rear window defogger.
Check that the rear window defogger works normally as follows.
1. Turn the ignition switch to the "ON" position.
2. Push the rear window defogger switch to operate the rear window
defogger.
Q: Does the defogger work normally?
YES: Go to Step 2.
NO: Because malfunction of the rear window defogger, carry out the
troubleshooting (Refer to MANUAL A/C DIAGNOSIS
).
