So I have this issue, pressing unlock on the key and in the car will lock the rear passenger door only, pressing lock locks the door as well. I can manually unlock it fine.

I took it apart and the spring is intact.

Anyone ever have this issue? I dont want to take it to the dealer...

My mechanic replaced the door actuator and it didnt solve it so they returned it. IS there a chance the new part was bad or is it something else?
