A/C Refrigerant System Component Description
A/C Compressor Regulator Valve
On A/C compressors without A/C Clutch (N25), the A/C Compressor Regulator Valve (N280) is integrated with the A/C compressor. Its function is
controlled by the Motronic Engine Control Module (ECM) (J220) in accordance with engine loads, speed and engine coolant temperature. The valve
regulates the low pressure (suction) side of the A/C compressor, thus controlling the evaporator temperature.
