The expansion valve is located on the driver side (US models) of the housing. Pull the lower dash by removing the bolts just under the steering wheel, and one further down, close to the carpeted section of the center console. Be careful when removing it, because the convenience light and wiring is attached to it.
If you look up, you'll see the lines coming in from the engine compartment and the expansion valve on the side of the housing. Whether you'll be able to R&R it without removing the dash and the whole housing is probably a 50/50 shot.
