Door lock

My guess is that you mean the left rear door. If all the rest work it may be the actuator assembly or an issue with the wiring or actuator linkage in the affected door.

I have 3 doors that doesnt open at the moment with the button or the smart key. It start with the driver back door , then passanger side and then the driver door. I think that it should be more than a actuator... any suggestions?

No. The passanger back door works fine. The driver, the driver passanger door and the passanger front door dont work. If i manually close the lock it stay lock, same if a open them manually(stay open). The working door i can close it with the beeper or the driver door button
