They do use the same bulb, but you need to access them from the front of the car.
Remove the plastic lens carefully.
Form the wheel well, remove the access plug.
Feel around for the fog light and pry it gently from the bottom up. It has a clip holding it in.
From the front, unscrew the fog light cover and now you can change the bulb.
Reverse to close it back up.
Be patient with the front fog light plastic cover, you may break off a tab if not careful.
