Passenger door lock issue

[toku.trax]

Have an issue with the power locks. The passenger door will lock and unlock fine if I use the passenger side button, but it won't respond when I hit the driver's door lock switch. It also doesn't unlock when I use the key in the driver's door. The strange part is the other three doors all work perfectly off the driver's button but it's only the front passenger side that acts up.
What's the deal with it ?. Its a 2019 chevy Trax
Thanks all in advance

Seems to me like the passenger door actuator or wiring is the problem, since it works from its own switch but not from the driver's side or key, the signal isnt making it through. I'd check the wiring in the door jamb first, and if that's fine, the actuator is probably on its way out.
