Inspection after Removal
Check the regulator assembly for the following items. Replace or grease it if a malfunction is detected.
Wire wear
Regulator deformation
The arrows in the figure show the application points of the multi-purpose grease.
FITTING INSPECTION
Check that the glass is fit securely into the sash groove.
Lower the glass slightly [approximately 10 to 20 mm (0.394 to 0.787 in)], and check that the clearance to the
sash is parallel. Loosen the regulator mounting bolts, guide rail mounting bolts, and glass and carrier plate
mounting bolts to correct the glass position if the clearance between the glass and sash is not parallel.

REFRIGERANT CYCLE
Refrigerant Flow
The refrigerant flows from the compressor, through the condenser with a liquid tank, through the evaporator,
and then back to the compressor. The refrigerant evaporation in the evaporator is controlled by an externally
equalized expansion valve, located at dash panels.
Freeze Protection
To prevent the evaporator from freezing up, the evaporator air temperature is monitored, and the voltage sig-
nal to the A/C auto amp. turns the A/C relay OFF and stops the compressor.
REFRIGERANT SYSTEM PROTECTION
Refrigerant Pressure Sensor
The refrigerant system is protected against excessively high or low-pressures by the refrigerant pressure sen-
sor, located on the liquid tank. The refrigerant pressure sensor detects the pressure inside the refrigerant line
and sends the voltage signal to the ECM if the system pressure rises above, or falls below the specifications.
ECM turns the A/C relay OFF and stops the compressor when pressure on the high-pressure side detected by
the refrigerant pressure sensor is over approximately 3,119 kPa (31.19 bar, 31.8 kg/cm
2, 452 psi) or below
approximately 118 kPa (1.18 bar, 1.2 kg/cm
2, 17 psi).
Pressure Relief Valve
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
The release port on the pressure relief valve automatically opens and releases refrigerant into the atmosphere
when the pressure of the refrigerant in the system increases to an unusual level [more than 3,600 kPa (36.0
bar, 36.7 kg/cm
2, 522 psi)].

Component Description
Compressor Intakes, compresses, and discharges refrigerant, to circulate refrigerant inside the refrigerant cycle.
Condenser Cools refrigerant discharged from compressor, and transforms it to liquid refrigerant.
Liquid tank Eliminates foreign material in refrigerant, and temporarily stores liquid refrigerant.
Refrigerant pressure sensor Refer to EC-348, "
Description".
EvaporatorThe mist form liquid refrigerant transforms to gas through evaporation by the air conveyed from the
blower motor. The air is cooled by the heat from evaporation.
Expansion valveTransforms high-pressure liquid refrigerant to mist form from low-pressure liquid refrigerant by the
drawing function.
Blower motorTakes in air from the vehicle or fresh outside air, provides it forcedly pushes it into to the air condi-
tioner, and circulates it inside the vehicle.
