Ford Focus 2006 ZX3 How do I replace the rear blinkers bulb

I know this might be a dumb question but, do you have the manual? The Focus owner's manual contains information on how to replace various secondary outside and interior lights.
When you open the hatchback look behind where the light is and you will see a small hole. Unscrew the screw that it is there. You also need to unscrew another screw that is beside the light on the outside (top right). Then you just pull the whole light assembly off the car. Next disconnect the wire from the back of the light bulb assembly. Next, twist the light bulb assemble and pull it out. You now have access to the bulb. Hope that helps.
