I was wrong that there was no orifice on my car, only have expansion valve instead of it. Where the expansion valve located? It is said to remove left lower quarter trim panel first by service manual.
Is it located on the front or rear of the car?
Is It locate at front of dashboard that I have to remove dashboard? Thanks for your help and instruction. What is technical difficulties?
If it contained these compartment?
Thanks!

How can I see it when it was behind of engine compartment, and have to remove all dash board from inside of car. I removed dash board follow repair manual. I think you should know well about the fact, there was no expansion valve on my images.

Sorry for the confusion. Here is the location and some diagrams to help you get the job done. It looks like it is right by the brake booster.
