From what he describes I don't think it's a pod problem, but it's easy enough to pull the glovebox liner and check all the pod hoses to make sure they will hold a vacuum. That's a hard thing to do since all your fingers are crossed while you're trying to test them. If the problem does turn out to be a pod, it's a 15 hour job to remove the dash and replace them. Don't even DREAM of replacing only the leaker, replace ALL of them.
