Rear dutch door lock

I don't see the question was ever enswered? I have the same problem, one side of rear hatch window will not unlock and see no way to take it apart to check anything. Can some please contact us with how to get this window open so we can repair this?

Thank you

The left lock on the top Dutch Door of my 99 Chev Astro won't unlock also. Pretty bad if you have a flat and can't crank down the spare.

You will need to crawl into the back of the van, and on either side of the hand hold in the centre, are caps covering two bolts, (10mm) if I remember correctly, remove them and handle. In the gap at the bottom of the interior panel of the hatch, you will see a metal arm, using a screw driver push it to the left as far as it will go. This is a pivot, that has a rod going to each side lock, and will release the hatch. Next take of the panel, ( screws on each end and some clips- its easy). Grease everything that moves. Also, make sure that the lock actuator is A) working and B) moving all the way, if not, check that the linkage is ok, and that actuator does not move instead.
