Open the trunk door and remove the carpet from the two tacks (right behind the License Plate on the inside) attached to it (twist the carpet out of it, I wasn't able to remove the tacks).
Disconnect the two-wire connection to the CHMSL unit inside.
You will need a 7mm socket to remove the two screws that attached to the CHSML unit. This will remove the black cover over the actual CHSML unit.
After the black cover is off, press the white/gray tabs in and push the CHMSL lens unit out (it will pop out outside of the trunk).
You now have the entire unit (Circuit Board, LED's and the Lens Cover) in your hands. You cannot replace the individual LED's as they are soldered behind the lens cover which is glued to the unit. Chevrolet states that you will need to replace the entire unit.
