pull the 4 bolts out behind the fan it will be hard but I did it in less than a n hour

I have come to be quite the expert with the trunk. Pull back all the carpeting from the inside, or as much as possilbe and stick a screw driver where the locking part is and slide the lock till it pops open. Then you must reassemble the assembly, which is pretty easy to figure out, that is located behind the carpeting on the trunk lid.
