    The facts:

    1. neither tail lamp lights
    2. licence plate light works
    3. front parking lights work
    4. both tail lamp bulbs are fine (visual and continuity both check)
    5. no power at the bulb socket on either tail lamp
    6. tail lamp ground in both bulb sockets is fine
    7. fuse under dash is not blown
    8. All brake lights work fine.
    9. All other lights working.

    Replace or continuity check the fuse again, plus make sure that the fuse you are looking at is the right one.

    This is a conundrum. The license plate lamps get power from a branch of the taillight circuit. So the fuse+body computer is not the problem. There isn't much wire from that branch point to the driver's side taillight socket. So the problem has to be in the wiring harness behind the driver's side trim panel, the big 2' by 4' piece. That's where the ground point is as well, even though that apparently is not the problem.

    Hi
    Check the 12v earth that sits below the hatch latch on the rear of the body.If you remove the spare wheel cover you will see it near the wiring harness below the latch.
    I have had a few cars that have chafed the earths and created problems with the tail lights.
