Removing Rear Door on 4000

[bossoj@rpi.edu (Joseph Charles Bossolini)]

I'm hoping someone can help me out.  One of the rear doors on 
my 82 4000 will not open.  There is a problem with the lock assembly (It 
looks as if the latch that the outer door handle presses on is
seized in the down position.).  I bought the car like this so I
am not sure what exactly caused this.  I have had my other 4000
do similiar things when someone tries to open the door while the lock
button is only halfway up.

Anyway, I have tried with no success to unlatch the door through the
inside.  I was thinking of trying to remove the door completely
but I can not find a way to loosen the door check stra.

Has anyone had any experience with similar problems?

Thanks
