NOTE:

The inner rear lamp unit contains two bulbs. The upper socket contains the tail lamp bulb, while the lower socket contains the backup lamp bulb. The service procedures for each bulb are the same, only the bulb sizes and types may differ.

Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable.
Open the liftgate to access and remove the inside trim panel from the lower liftgate. Refer to PANEL, TRIM, REMOVAL .
Firmly grasp the appropriate bulb socket (2 or 3) on the back of the lamp housing (1) and rotate it counterclockwise about 30 degrees to unlock it.
Pull the socket and bulb straight out of the lamp.
Pull the base of the bulb straight out of the socket.
