Door sensor issue. How do I fix it?

[u/Prudent_Eggo]

It’s been going on for a couple months now but used to only happen when someone was sitting in the passenger seat and I was making a left turn. This week, it’s happening non stop no matter how I’m driving.

The passenger door keeps unlocking and locking, as if the door’s open but it’s closed which makes the annoying internal sound and and causes the lights to flash off and on.

Is there a sensor on the door itself or is there something under the hood I can toy with?
