BLOWER UNIT : Removal Installation 114, bLOWER MOTOR : Removal Installation 115, lOW-PRESSURE PIPE AND HIGH-PRESSURE PIPE 2 : Removal Installation 101, verify the symptom with operational check.
(WITHOUT ACCS) or HAC-8, "WITH ACCS : Description & Inspection" (WITH ACCS), go to appropriate trouble diagnosis [Refer to HAC-154, "Diagnosis Chart By Symptom" below], repair or replace specific parts, the refrigerant flows from the compressor, through the condenser with liquid tank, through evaporator.
Expansion valve, located inside evaporator case, to prevent evaporator from freezing up, the evaporator air temperature is monitored, and voltage signal, the unified meter and A/C amp, the refrigerant system is protected against excessively high- or low-pressures by the refrigerant pressure sensor, located on the liquid tank.
And sends the voltage signal to the ECM if the system pressure rises above, or falls below specifications, the high-pressure side detected by refrigerant pressure sensor is approximately 3,120 kPa (31, psi) or more when the engine speed is 1500 rpm or more, when the engine speed is less than 1,500 rpm.
ECM turns the A/C relay to OFF stops compressor, the refrigerant system is also protected by a pressure relief valve, located in the rear head compressor, the release port on the pressure relief valve automatically opens and releases refrigerant into atmosphere.
