The tailgate glass does not open on my Estate/Wagon. I thought it would be nice to fix this so I found the section in the workshop manual with instructions. First remove the rear wiper. Easy peasy. The next steps require the glass to be open. Except it doesn't open because the latch isn't working... It looks like the glass also holds the tailgate panel (the plastic cover bit that would be a "door card" if it was a door) captive so I can't open the entire tailgate and work my way in to the latch. Am I done for or is there another way to unlatch the rear window glass?

 

Here are some TSBs we got for tailgate issues.
