complete mechanism as the cable is part of it - dont panic though
as new one genuine is roughly only £40 and second hand (breakers) probably half that or not less
once the door trim is off its an easy job to change - i think m0rk gave it a 2 spanner rating ?
PS - when you do change it hold the glass up with duct tape over the door frame to save buying a new glass as well when you drop it
