I forgot to mention - my Jeep is at the paint shop until Christmas having its corrosion on the doors and hood corrected. So I couldn’t fix the door ajar issue right now even if I wanted to lol. 84 hours of labor…. Luckily still under the corrosion warranty.

Did you ever solve this issue?
I'm having the same problem on my 2018 JL - driver side passenger door.
It doesn't recognize if the door is open and doesn't turn on dome lights.

I went through the wiring diagram and found that the lock actuator assembly is what’s responsible for triggering the door ajar, unlike most vehicles that have a dedicated sensor. I bought the actuator and still haven’t installed it. Been on the back burner for a while but I’ll probably replace it in the next few weeks. I’ll let you know if it works. I assume it will.

Pretty much no vehicle has a door ajar switch anymore. It has been something like 20 years on that.

Now I’m going to have to check my other vehicles. Didn’t realize that. My first gen sequoia has one and I haven’t noticed in my ‘24 pathfinder.

When is a door not a door?

When it’s ajar.
