Howdy, folks. I'm having the *EXACT* same problem as Grogzero did. Started a week ago, when the hatch would refuse to open. I could pop the rear glass open, and that alone would "loosen" up the hatch so that it would unlock. today, when I tried to open the glass, it had some resistance, then I heard a "pop" sound. Doh.
Ended up having to crawl in and move the little white plastic locking lever from inside, as Grogzero described. Now I can open the rear hatch, but it requires crawling in each time. And the rear glass seems to be permanently locked.
Any advice would be greatly appreciated. Anyone have any guides/DIYs/step-by-steps on how to take the rear hatch apart? part #s?
