The expansion valve is the end of the high pressure system and the beginning of the low pressure system. After the valve is the evaporator. If there is no flow to this area, my suspicion is that the expansion valve is blocked in some fashion.
If there is flow, but it's not satisfactory to cool the vehicle, then Arthur's suggestion that the system is full of air is valid.
