i have the capability of checking these with a scan tool, but if you dont have a enhanced scan tool i would just recommend lubing them all. you can lube them one at a time and open/shut door a couple of times to see which door is the culprit.

the ajar switches are located inside the door and mounted to the bottom of the latch. all you need to do to lube them is take and spray can of penetrate/oil or silicone spray, then open the door and spray directly into the latch and then gravity will kick in and soak it into the ajar switch. you can actually take a screwdriver and work the latch claws open/shut if you hold the door handle too. or just open/shut the door a few times to remedy. i recommend doing one door at a time just so you can verify which one was sticking.

also i dont know off the top of my head but some models will give you an extra chime once when a door is opened with the key-on or engine running. if all but one door chimes once when opening then the faulty switch is on the door that doesnt give the extra chime.

Spray all door latches with WD40, open and close several times repeating application of WD40.
