POTENTIOMETER CHECK While checking the mode selection damper control motor, measure the resistances
between terminal numbers 3 and 5 and between terminal numbers 3 and 7. At this
time, the resistances should change gradually within the standard value. Standard value: 0.8 (DEF) - 4.8 (FACE) kohm

OUTSIDE/INSIDE AIR SELECTION DAMPER CONTROL MOTOR CHECK Check the outside/inside air selection damper control motor by the following
procedures. Fig. 291: Identifying Outside/Inside Position Of Air Selection Damper Control
CAUTION: Cut off the battery voltage when the damper is in the
inside/outside air position.

INSPECTION AMBIENT AIR TEMPERATURE SENSOR CHECK
CAUTION: The ambient air temperature sensor should be
checked with removing it. If the sensor is removed, it
is no longer serviceable.

To prevent the entry of dust or other foreign bodies, plug the dismantled hoses and
compressor nipples. << B >> COMPRESSOR REMOVAL Take care not to spill any compressor oil when removing the compressor. INSTALLATION SERVICE POINT >> A << COMPRESSOR INSTALLATION If a new compressor is installed, first adjust the amount of oil according to the
procedures described below, and then install the compressor.
1. Measure the amount [X cm
3 (X fl.oz) of oil within the removed compressor.
2. Drain (from the new compressor) the amount of oil calculated according to the
following formula, and then install the new compressor.
New compressor oil amount = 140cm
2 (4.7 fl.oz)
140 cm
3 - X cm
3 = Y cm

: 60 c
m3 (2.0 fl.oz
)
CAUTION: As the compressor oil and receiver are highly
moisture absorbent, use a non-porous material to
plug the hose and nipples.
NOTE:
Y cm
3 (Y fl.oz) indicates the amount of oil in the refrigerant
line, the condenser, the evaporator, etc.
NOTE: When replacing the following parts at the same times as the
compressor, subtract the rated oil amount of each part from
Y cm3 (Y fl.oz) and discharge from the new compressor.

INSPECTION COMPRESSOR AIR CONDITIONING COMPRESSOR CLUTCH OPERATION CHECK Connect the compressor connector terminal to the battery positive (+) terminal and
ground the battery's negative (-) terminal to the compressor unit. At that time, the
air conditioning compressor clutch should make a definite operating sound. Fig. 298: Checking A/C Compressor Clutch
