AC Pressure Sensor For S3 2012 4H0959126A 4H0959126B A/C Switch

Real-time pressure monitoring: Continuously monitors the refrigerant pressure of the automotive air conditioning system and transmits the signal to the vehicle, providing a reference for the operation and control of the compressor and cooling fan. Improved cooling performance: Replacing faulty or malfunctioning sensors helps restore normal pressure monitoring and improves problems such as the air conditioning not cooling, intermittent cooling, or the compressor failing to start. Material: The air conditioning pressure switch sensor is made of metal and plastic materials, which is strong, sturdy and practical; Function: The car air conditioning switch can prevent the refrigeration module from working under extreme refrigerant pipeline pressure and help control the speed of the engine cooling fan; OEM part number: 4H0959126B, 4H0 959 126, 4H0 959 126 A, 4H0 959 126 B Please check the part number of your product carefully;
