Its behind the driver's side fog light. Looks like a thermos. I'd say about 10" tall 3" round. I got quoted $85 to recharge my AC last summer. Still haven't done it yet but $164 is a ripoff.
Looking on SLM parts Receiver/Drier(I think thats the right part) goes for $70 to $93 US depending on the vehicle.
Hope that helps !
