Hi, I'm Mike Green from 1A Auto. Today, I'm going to show you how to remove and replace the headlights on this vehicle. It's a 1999 Suburban. It's generally the same as a 1988 to 99 Chevy or GMC truck, as well as the '92 to '99 Suburban, Yukon, the 2-door Jimmy full sized, and the Tahoe. With that, the first thing we're going to do is open up the hood to access the headlight.
If you're looking to replace your light bulbs, locate these two five millimeter studs. Remove them with socket or a wrench. Your light comes out. You have access to the back of the headlights. You can just unplug the low beam and the high beam and replace the bulbs. If you're looking to replace the headlight assemblies, stay with us. We'll go into more detail on that. In behind there's a mounting plate; if your headlight's been damaged, normally this mounting plate is damaged also. If we want to replace the whole headlight assembly, we'll have to remove the grill.

To do that, what we do next is remove the parking light. It has four Phillip's screws that we take out. Okay, let's speed this up a little bit. You remove the light. You just click the thumbs and twist and pull the lights out. Your parking light's removed; the opposite parking light. There are ten screws which we're going to quickly show you on the grill. These screws hold the grill in, two behind the parking lights, two in the middle, two behind the opposite side parking lights, and then four up top. I got the 10 bolts out. You can see the headlights are still in. The marker lights are still in, but they are unplugged. Once those bolts are out, you can pull it forward. Just make sure everything comes apart in here. Bulbs and stuff are clear. The grill's out, separate.

You can easily unbolt your headlight assemblies. From here we're looking at the driver's side headlight assembly, we'd remove this bolt, this bolt, this bolt, and this bolt. Going to unplug; your headlight's free. This is the new headlight assembly. Okay, and quadruple time. Shops charge 50 bucks an hour for this stuff. This has got to be worth 200 bucks an hour anyways. Look at that hand movement. I don't even know if tools move that fast. Now that the light's bolted in, we can connect the headlight harnesses. Once the headlight harnesses are connected, we'll reach into the cockpit real quick. Test the low beams, click on the high beams. Oh! Everything looks good.

We can put the grill back on, just reverse your procedure. Tilt it in there. Pull the lights through first, each side. Tilt it in. There's a little harness in the center, too. Make sure that doesn't get pinched in there. Push it up in. The top, the plastic lip goes up over the top of the sheet metal. Once everything looks right, we'll bolt it back in. You're ready to go. Ten they're seven millimeter bolts. We've re-installed the grill. We need to reinstall, we need to plug in the markers and install the parking lights. We're now back in close-up. This you put in and you twist. These go in just like they came out. You get them to click as they lock into place. A shot of espresso or two.

There I am standing in front of the truck. My lips aren't moving. I am talking to you through the magic of computers. We hope this video helped you out how you can see we got our lights back in. Our grill's on and our parking lights.

We're going to remove the four mounting screws for this lens assembly right here. Slide this out of the way. Now, we're going to remove the mounting bolts that hold on this whole plastic grille assembly here. All right. So, there should be one. Should be one here. All right. Now that we have those bolts out, let's go ahead and give this a little tug. This gives us plenty of space. Now, if you were to look right here, you can see one of the mounting bolts. You can see another one right over here. And then if you were to come right down through here, you're going to find another one and another one. Remove all four of those. We'll get the headlamp loose. Then we'll remove the wiring that goes to the bulbs.

All right. At this point, we can move this around quite a bit. Get these right out of here, sockets. Carefully set that down. Do the same thing here. See if I can get this one out. For this one, it's going to be much easier just to get the wiring off first, and then you'll be able to turn the bulb to be able to remove it. Take a look at that bulb. If you need to replace it, now's a great time. See if we can weasel this out of here now. There it is, friends.

Now, if you look at the top of your headlamp assembly, you're going to notice this adjustment right here. This is to make your lamp assembly go left and right. And this one right here is to make your lamp assembly aim up or down. Just keep that in mind.

So, now's a great time to go ahead and install your bulbs. If you wanted to get some new ones, perfect. Gonna take this, wan to to carefully try to work it so it goes inside here. Fall right in. Okay. So, now, I'm just gonna rest it like this. I'm going to reconnect in my wiring. this one. Come on. Try to grab it here. All right. So, you've got a longer wire and a shorter one. The shorter one's obviously going to go to the closer area. Something that's important to pay attention to is the wiring goes behind this bracket right here. You don't want to put it on the other side because it'll get crushed when you go to mount this in. The other wire, same thing. Behind, that looks great. Now, we're going to put this up against the body. We're going to line up those bolt holes and then we'll start in all of our bolts before we tighten any of them down.

All right. So, now's a perfect time to align those headlights. The reason for that is because the alignment points, like I said, are located right here. And if this is in the way, well, you're not gonna be able to get to them. It's time to get these bolts back in. I'm just going to start it in. We'll start them all in and then we'll snug them up.

All right. Let's tighten them all up. That one didn't hold very well. We'll line it up. Oh yeah, that looks great. Let's get our screws in. Okay. Now, I'm just gonna snug them up. Beautiful.

This is going to be a general tutorial on how to aim your brand new TRQ headlamp assemblies. Okay. So, looking at your brand new TRQ headlamp assembly, you're going to see where your low beam is, and you'll see a little dot right in the center. And that is the access point, okay? So, what we're going to do is we're going to mark that with an erasable marker just so it's easier to see. Next, what we need to do is measure from the level ground up to this point and take note of that measurement. Now, we're just going to pull the car up to our wall. On our vehicle, we remember that the measurement was 28 inches for our access point. Your vehicle may be different, but that's where I'm going to put this tape. Just above that 28 inches. We'll do same on the other side. Okay. So, let's just back the vehicle up straight back 25 feet from the wall. And now that we moved our vehicle 25 feet back from the wall, we're going to start with our measurement here. That's where the headlamp center is. We're gonna go down 4 inches on the driver side.

On the passenger side, we have our line here. What we need to do is go down 2 inches. To adjust the driver side, we're going to cover our passenger side headlamp. If you look at the backside of your headlamp assembly, you're going to see something that looks like this. This is the adjustment. Some of these headlight assemblies have one, two, or even more of them, but you should at least have one. This is how we're going to adjust the headlight beam. Now, we're going to lower the top part of the beam down to just below this line. When you turn the adjustment to the right, it brings the beam up. And if you turn it to the left, it'll bring the headlight beam down. And this is this way on most vehicles. Let's continue on to doing the passenger side. All right. We properly aligned our TRQ headlamp assemblies.

Okay. And on the quality TRQ headlamps for a pickup truck, the procedure is going to be the same. You're going to find your center dot, mark it, and then you'll measure from the level ground up to your dot. So, once your headlamps are properly adjusted, it'll be time to adjust your fog lamps. You'll notice on the driver side, the focal point is all the way at the bottom right now. I would like to bring it up so it meets up with approximately the bottom of the focal point of the headlight. Some fog lamps have an adjuster, others don't. The ones that do have an adjuster, you would just turn the adjustment to the left or to the right to adjust the beam up and down to where it needs to be. Now, with your TRQ headlamps and fog lamps properly aligned, you can drive down the road safely.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to service the headlight bulbs as well as replace the entire headlight assembly on this 1996 Chevy Tahoe. We show you on the passenger side, but the driver side is the same procedure. The items you'll need for this include new headlights from 1AAuto.com, Phillips screwdriver, and a 7mm and 10mm socket and ratchet with an extension.

You want to first remove these four Phillips screws, and we'll just fast-forward as Don does this. Pull the light out, twist the sockets counterclockwise, and pull them out. Then, you want to twist this socket out of your side marker light, and then repeat the process on the other side.

Next, you want to remove this series of 7mm bolts, and we'll just fast-forward as Don does this. There's one more 7mm bolt right here. Once those are removed, you want to just lift up this tab, pull the grille forward, and there's another one on the other side. There's another clip right in the center. Using a stick or a long screwdriver, you just want to push that tab and then pull out on that center tab. Just to give you a better look at it, it's this tab right here.

Next, you want to remove these four 10mm bolts that secure your headlight, and we'll just fast-forward as Don removes those. Now, to service your bulbs, both of them are the same. You just pull back this tab and pull the harness free, then twist the bulb out. Push the new one in, twist it clockwise to lock it, and then just reconnect your harness. If you're looking to replace the whole assembly, you just want to disconnect both of these harnesses by pulling up that tab.

Then take your new headlight and push the harnesses into place. Then push your headlight back into place and replace those four 10mm bolts. Once those are in place, take your grille and pull your parking light sockets through, and then you want to line up the tabs on the grille.

The first one you want to do is the center one, and just push down that tab and push the tab on the grilled into place until it locks. Now, line up those side ones and push those into place and we'll just fast-forward here as Don replaces those five 7mm bolts. There's four along the top of the grille, and then that one in the center just above the badge.

Now, twist your side marker light back into place. Then twist your two parking light sockets back into place, just turning them clockwise to lock them. Then push the assembly into place and replace those four Philip screws. Repeat the process on the other side.
