Rear passenger door central locking not working?

For several reason you decided not to give the make and model of your car, so we can't do the Internet search you could have to see if there are common problems with your particular car.

It sounds like a wire may have failed, possibly where cables pass between car body and into the door.

You may well have to take the door card off

Find a forum specific to your make of car (and specific model if possible) and ask there
