rear glass on dutch door on 1996 Chevrolet Astro

The nrear window on my dutch stop does not release on the passenger side. Therefore the rear door cannot be used. How can I get it open?

If you remove the inside trim panel from the lower door you will be able to access the rods that go to each side latch. I would suspect that the passenger side rod has come loose from the lever. Pulling on the rod should release the latch. There maybe a top section of the lower door panel which will allow access to the rods or the complete lower panel may need to come off.
