Ding Ding Ding Ding Ding....

We have a winner!!!!

After pulling the switches out of the rear hatch and cleaning them, pulling apart the barn door latches and realizing that there's no switches in them, and cleaning the locks on the passenger side, it turned out to be the rear door on the driver's side.

That's time that could have been better invested. But at least it's all good now....

Congratulations!
Always feels so much better to diy than pay somebody who is as clueless about it at the start! Now you possess valuable knowledge AND shared it with us. Thanks for the update.

it's annoying. Some say to spray the locking mechanism with wd40. Tried that but doesn't seem to help much.
So what is up with the slam hard method? What is actually not working right in there? I asked before and got no answer, everybody just keeps slamming. (Including me).

Apparently, as the switches get clogged with dust and dirty, they stick a bit and don't move their full range when you normally open/close the door. Slamming the door jars them just enough for the contacts in the switch to move far enough to open the circuit.

The door ajar sensors are a poor design. To see the actual sensor search NAPA and you'll see it. Anyway, the goal of slamming the door is I jar the sensor spring, but the main issue comes from dust getting in the sensor and fouling the internal contacts.

By actually pulling the sensor out of the door you can use cleaners to flush out the dirt and get it lubed up. The latch applies pressure to the sensor in a poor way with a plastic lever. Nevertheless, a good cleaning will last a long time.
