|It sounds to
me like the door latch is the problem, or the
connecting link rod between the handle and the
latch. Ford uses plastic lock clips to attach
the rods to the latch and to the release
handles. One of those plastic pieces could be
worn or broken. Also, the entire latch mechanism
could be worn out. Once the door panel is
removed this should all be easy to diagnose.
Getting inside the door panel is very difficult
when the door cannot open. I've had to do this
before, and it has taken me several hours to pop
open a stuck door. When faced with this problem
in the past, I have removed all the screws that
I can reach, and pry out all the snap clips that
I can reach, and then try to pull the door panel
upwards so I can unhook the panel lip at the
top. Then I reach inside and try to jiggle the
linkage rods until the door pops open. This is
time-consuming and frustrating work. Sorry.
I wish it was easier. Best of luck.
