Does anyone know of any videos or if I would be able to replace the rear tail lamp assembly by myself going through the trunk? There is a dime-sized hole where something hit it and water is getting in so I probably need to replace the whole thing. I have clear tape over it now, but there is condensation built up inside. Any help would be greatly appreciated.

I believe you will have to loosen the rear bumper at a minimum (or completely remove the bumper) to get to the screws that hold the tailight on.

 

peel back the lining inside the trunk and remove 3 screws hold the tail lamp. it should be 3x1 inch hex screws. use a adjustable wrench. push from the back and it pops out.. thats it.

 

^^ What Potz said is correct. No need to remove the bumper. Also loosen all the hex nuts most of the way but don not completely remove them, then tap on the nuts to loosen the light assembly from the frame of the car. After that you remove the hex nuts, twist off the bulb connectors and then remove the light assembly.
