AC Expansion Device

The expansion valve is an important part of your car's AC system for regulating refrigerant. The liquid refrigerant entering the expansion valve is warm and gets cold when it passes through the valve. The main function of the expansion valve is to convert the refrigerant into vapor by removing the pressure and expanding the gas. It is located on or near the AC evaporator. It has a rod that opens and closes a passage which allows the refrigerant to move inside the valve. The position of the valve varies and modulates between fully opened and closed states to precisely regulate the amount of refrigerant going into the AC system.

You need to replace the expansion valve immediately if there is a blockage or if it is stuck open. These issues can result in low or high suction pressure.
