Central locking passenger side defective

Hello, I need your help again. My moose has a defect with ZV on the passenger side. Regardless of whether with remote control or key does not close and opens the passenger door. In addition, I noticed in the dark that when opening the passenger door the interior lighting does not concern. In order to unlock the door, I always have to pull up the pen from the inside and pull it down with my hand to lock it. Now I have already read that the actuator in the lock can break off. Since I noticed the light, I thought about the electronics. The red door light doesn’t shine anymore, but the mirror can still be adjusted normally. Maybe it’s worth noting that the driver can lower the window on the back right, but high only from the back is possible… Thanks already for your ideas and tips LG
