Did you have your system Diagnosed and are you sure that it is an expansion valve problem? Because it is very important to have the system properly inspected before you start replacing parts, which can be very expensive.

check you can see refrigerant in the sight glass on the reciaver drier when the system is on . sometimes under load and low rpm the a/c system will shut off to prevent the engine stalling . check if it works around town then on over a constant distance
