I just had the liftgate recall done on my 2002 about two months ago. I had the leak around where one of the hinges mounts to the glass, i know this becuase I could see it running down the glass from aorund the bolt. Beware when you go to have it done. My dealer told 45 min to 1 hour, I was there almost 3 hours.
On a side note. Now that I have had the recall done every time it rains I get water in my cargo liner and we have yet to figure out where that is coming from but it's not from the hinges. I don't know that is related as I only owned it a couple days before getting recall done and until recently it was garaged while at home and work.
