Does anyone know why I would be smelling gas when I run my a/c. I usually don't run it but my wimpy friend who has to have a/c talked me into running it in Japan's rush hour traffic while on our way for him to look at a new Subaru Impreza. It wasn't a strong overpowering smell but it was a noticeable smell. Not to mention my full pump was still going after I shut the car down when we got to the dealer. Any ideas??
