Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the third brake light on this 2003 GMC Envoy XL. It's the same part and similar process on the regular Envoys made after 2002. The items you'll need are a new third brake light from 1AAuto.com, a flat blade screwdriver, and a Phillips screwdriver.
Lift up your lift gate and pull on this grommet. Then, just keep pulling the harness out until you can get to the connector. Using a flat blade screwdriver, pry out on the tab and disconnect the harness. Now, open up the glass and remove these three Phillips screws. We'll just fast forward as Mike does that.Then, just pull the grommet and the harness up through this slot. Then, unclip it, and then just pull the third brake light down and out.
Up top, is the old third brake light. Below it, is the new one from 1A Auto. You can see they're identical and they'll fit exactly the same. Feed your new brake light up into place, and then replace those three Phillips screws. Now lift up your lift gate with the glass still open, and then just feed the harness down through the slot. Once you get it going, just open up your lift gate and pull it down and through the rest of the way. Make sure that it's on the right side of the hinge. Then, reconnect the harness and feed it back down into the hole and push the grommet back into place. Now, just test it out. You can see it works, so you're all set.
