the expansion valve is above your right knee. pull the wheel, pull the cluster, pull the knee bolster and trim panel on tunnel. then you can see it. they are a MOTHER to remove. very tight fittings and very tight working space. you need a wrench to hold the valve still as you wrestle with the fittings. you need line wrenches for the 4 nuts on 4 pipes, soft, bendable pipes. especially on the evap. good luck, chuck.
