There are several discussions here, you need to use the search function. First have a
look here, if you find that the fuses are broken. But there might also be broken wire in between the door and the car. Tesla have had one door controller module per side (placed in front doors) on older cars but yours might already be with the gen.3 door handles so it should have separate module for rear doors.
Edit: And
here is one about that broken wire situation.
