there is a small round plug that needs to come out behind it is a screw.
there is a screw behind the latch handle and one in the door cup there is
also one behind the power window switch bezal that must be popped out of
place
sometimes there is screws in the bottom of the door panel if you have the
big map pocket one you are sure you have all the screws the door panel just
pops off with a good yank
the lock actutor is part of the door latch and i would bet it made a
whirling noise for a while
