The AC Expansion Valve (OEM Part Number: 1668300284) plays a crucial role in the air conditioning system of various Mercedes-Benz models, including GLE and GLS series vehicles from 2012 to 2019. Located within the refrigerant lines, it regulates the flow of refrigerant entering the evaporator, ensuring optimal cooling performance. This component works seamlessly with the compressor and evaporator to convert liquid refrigerant into a gas, facilitating heat exchange for effective temperature control. If you experience issues such as warm air from the vents, inconsistent cooling, or refrigerant leaks, replacing the expansion valve is essential. Compatible models include the 2019 GLE400 and GLS450, as well as earlier models like the ML350 and GL550.
