Two cables operate the door lock and door pull handle — a blue cable for the door lock, and a black one for the door pull handle. Each cable has a plastic sleeve that needs to be disconnected, as well as a metal cable ball that has to be de-routed from the door handle.
Firmly grip the plastic blue sleeve and disconnect it by pulling it perpendicularly away from the plastic bracket.
Lift the sleeve upwards so that the metal ball at the end of the cable is removed from its housing.
Pull the entire cable away from the door panel.
