Where is the expansion valve on an AC unit?
The AC expansion valve is found within the air conditioning system of a vehicle. The purpose of the valve is to manage how much refrigerant liquid can flow throughout this system. Whenever there is an abundance of refrigerant, the core of the evaporator will get too cold and eventually freeze.
