Hey I just changed the drier on my 02 impala. Now it's my understanding to also change the oriphics tube, also known as the expansion valve but I can't seem to locate it . I checked the lines from compresser to condenser then from condenser to fire wall an no luck if can help. please.

It is located in the "low" pressure or suction side. It should be near a connection and there will be "dimples" in the line, they hold the orifice tube in place.
