A/C & HEATER SERVICE PROCEDURES FOR 1997 BMW 750IL AUTOMOBILES
BMW -> Manual A/C & Heater System Diagnosis & Testing -> Description -> 325 -> A/C Compressor Switch -> Air Center Control Lever -> Air Down Control Lever -> Air Up Control Lever -> Air Volume Control Switch -> Fresh Air/Bypass Air Switch -> Refrigeration System -> System Control -> Temperature Control
Vehicle: 1997 BMW 750IL 5.4 V12 GAS
Refrigeration System
Switching on the A/C system will activate the refrigerant circuit, Fig. . The solenoid coil receives power, producing a magnetic field causing the armature clutch plate to be pulled, and which is fixed onto the compressor shaft next to an inner plate operating freely on the same shaft. The compressor increases refrigerant vapor pressure, which is drawn into the suction end of the compressor assembly. The refrigerant is then compressed, raising refrigerant vapor temperature. The high pressure vapors pass through a high pressure line to a condenser loc...
