93 ford aerostar rear cargo door wont open

the handle for opening the back pulls loose and the door will not pop open,i believe it has dettached from the locking mechanism. any advice as to how to open it now?? PLEASE HELP GUYS!!!

You’ll have to remove the inner door panel, which won’t be easy if you can’t open the door, to get at the latch mechanism.

You may have to cut through the panel and find a replacement in a junk yard.
