That all depends on why it is stuck. if you have  power door locks the lock
actuator may be seized up and wont unlock it. you would have to disconnect
the rods and unlock it that way.
If the torx screws came loose at the latch assembly and causing it to stick
you got serious issues then. you would have to reach way back and try to
hold it while opening the door.
Once again without seeing it would be hard to say what is wrong, and there
is no special release.

Had the same problem with mine.  The problem is related to the gas door
on that side.  Our door was slammed shut extra extra hard one day and
that actually bent the rod that actuates the gas door - it's a safey
mechanism that prevents you from opening the sliding door when you are
gassing up.

Low tech solution:  Remove middle seats from van - you'll need the
room.  I was kidn of laying on the floor of the van and had someone
else push the button on release handle as if I was opening it then as I
lay there on the floor of the van I gave the door  (the rear portion
closest the gas door) a swift kick and it popped right open.  Of course
I immeditately closed   it again and got it promptly stuck again.  But,
another swift kick got it open.  Once it's open look on the rear of the
door closest to the gas door and you will see a small rod that goes in
to that panel.  I think there were two bolts (might have been torx
heads) and I took the rod out.  Door works great now.

Good Luck!
