If it's anything like the 01 I just worked on there is a LOT of plastic
in the door latch/lock assembly and some of it looks easy to break. The
inner knob actually moves a plastic tab into position that blocks the
latch. If that broke it would cause this type of problem.
Take the inner door panel off and look. It is easy and fast. Refer to the
manual. Essentially, remove 4 or 5 screws and lift the panel up, then out.
Simply unplug the electrical connector for the window controls. The panel is
held to the door with plastic inverted "L" clips Don't force it.
