Glove Box door of Nissan 1994 Pathfinder XE won't open

Whether locked of unlocked, the glove box door won't open. I have used a knife and slot end screwdriver on the top edge of the door coupled with 'out and downward pull' on the door handle to try to open it. I stopped after applying significant pressure with both the screwdriver pry and the handle pull, fearing that I would do further damage. There's nothing in my Chilton's manual about Pathfinder Glove Boxes. Do you have any suggestions?
