This year does not use an orifice tube but a expansion valve instead. This is located under the hood on the passenger side where the Refrigerant lines go into the evaporator under cowl (dash area) looks like an aluminum block. If it did have an orifice tube it would be located in the same place only inside the high side refrigerant line, or the smaller of the two lines and can be unbolted and separated to get to the orifice tube.
