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 service the bulbs as well as replace the entire taillight assembly on this 2003 GMC Envoy XL. It's the same part and similar process on the regular Envoys made after 2002. We show you on the passenger's side, but the driver's side is the same procedure. The items you need include new taillights from 1AAuto.com and a Phillips screwdriver.
Start off by opening your lift gate and removing these two Phillips screws on the inside of the taillight. Pull the taillight out, tilt it back, and then you just want to push the tab on this harness and disconnect it.
Now, to remove the circuit board, to get to the bulbs you just need to remove these three Phillips screws. To service the bulbs, just pull the plate out and then you can just pull the bulb straight out and push your new bulb into place. These two are the same process.
Now, you just push the circuit board back into your taillight, replace those three Phillips screws, and tighten them up.
Now, if you're looking to replace the entire taillight assembly. On the right is the old taillight; on the left is the new taillight from 1A Auto. You can see they're identical, and will fit exactly the same. The only thing you have to do is swap over this plate. Just push in the tabs on the plate, pull it off, and then push it into place on your new taillight.
You can see there's two holes right here and they should have clips in them. One of them does, one of them is missing. Sometimes they come out with the taillight, so just pull them off that pin on the taillight and push the clip back into place. Then line up these two pins, and you're going to push them into those holes.
First reconnect your harness, and then push the taillight back into place. Then replace those two Phillips screws. You're all set.

Okay, friends, to get started on doing your rear tail lamp, you're gonna need a Phillips head, and you're also gonna need a nice plastic trim tool. Use your Phillips head and remove the two mounting bolts. Use your trim tool, come right down along the lamp and the body, and just draw it away. At this point, we're gonna remove the wiring. If you just come right here, you can squeeze on this tab right where my thumb is, and then you should be able to draw this off. Take a peek. Make sure you don't see any funny colors.
Next, we're gonna remove this trim piece from the lamp itself. If you were to turn it over, you're gonna see there's a little clippy-do here and here. If you press down on those just a little bit, you don't want to break them off, you should be able to draw the trim piece away, and you can do the same with these ones right here. Let's put this on the new lamp.
All right, friends, here's our new lamp assembly. As you can tell, we have to insert that trim piece. This is great because you don't have to worry about color-matching anything. You just put on the piece that was already existing. Line up the holes. Squeeze it in. Make sure it's completely clipped in all the way around and it's completely secure.
Now, if you were to look at the backside of the lamp assembly, you're gonna see that there's a couple little pitons. Those need to go into these holes right here. Okay? With that said, let's grab the wiring, connect it in. Give it a nice tug. Make sure it's secure. It needs to be secure. Line up those pitons with the holes that are on the body, and then go ahead and give it a light bonk just to set it in. You wanna make sure it's lined up all the way around and your mounting holes are lined up as well. Insert your mounting screws. Make sure they're nice and snug. Now give it a test.
