Only way to tell if A/C Evaporator Core Orifice tube is plugged is by looking at A/C gauge readings , An if it is plugged you more then likely need a new compressor , they become plugged with metal particles from worn out compressor. Your best bet would be to take your vehicle to a qualified repair shop .
