In this video, we are going to show you how to service the bulbs as well as change the entire inner taillight assembly on this 2014 GMC Terrain. The only tools you'll need for this is a flat blade screwdriver and an 8mm socket and ratchet. Open up your trunk and you want to start off by removing this plastic panel right here. To service this bulb, you just twist the socket out and pull it down. The bulb pulls right out and you can push your new one into place and the socket just twists back into place.

Now to change the assembly, you're going to have to remove this harness, just push the tab and pull it free. Next, remove this series of 8mm bolts, there's two here, one here, one here and one more on the outside here. We'll fast forward as Don removes those five bolts. Once those are removed, push from the backside of the taillight and pull up and it should pull free. To service these other two bulbs, you just twist them out, bulb pulls out and push your new one in and twist back into place. This one's the same. Take your new inner taillight line it up and push it back down into place and replace those five 8mm bolts. Reconnect your harness. Then snap that plastic panel back into place. Then you are all set.
