it seems like every summer intermittently my wife said when shes running the a/c she will get a gas smell inside the blazer.we had it to garage no fuel leak at all.ive checked it several times but of course it never does it when im there.it doesn't do it all the time.and of course when I drive it around with it on it wont do it.any ideas or anyone else have this problem?
