rear door on 1994 Ford Aerostar

door lock stopped working on rear hatch. I close hatch and door won't hook to latch.

Sounds like two issues - the door lock actuator may have failed. And the latch seems to either be out of adjustment or has failed as well, if it won't hook to the latch.
try spraying some good old fashioned silcon lubricant into the mechanism. I occaisionally have the same problem. A little lubricant will work for amny months. Mine may freeze up during the winter months.
