How do you replace a broken tail light assembly on a 2005 Buick Lacrosse?

Answer 1

I've got a CXL, with the cargo netting, I've changed the bulbs before, this is what I had to do in mine. Not sure about the CX or CXS assemblies.

Pull back the felt lining in trunk, removing the hooks for the cargo netting, you should see something like 3 or 4 thumb screws. Remove them, push on the long bolts where the screws were, and it should push out. After that, just disconnect the wiring harness and attach the replacement part, or just pull the lights out of the plastic and reattach the lights to the new cover, depending on how you got your assembly.
