I did a search for the door ajar problem on the Rangers and the fix being spaying WD-40 in the latch. I wanted some clarification. Do you spray WD-40 in the "latch" on the door jamb, or inside the door handles, or remove the door panel and spray inside the door on the switch inside? Thanks.

You spray directly on the latch. It makes it's way down to the switch, which is mounted to the bottom of the latch.

I had this problem too and WD40 in the door latch opening did the trick. After a frustrating search I couldn't believe how simple the fix was. Worked on my Sable too.
