In this video, we're going to be working with our 2012 GMC Acadia. We're going to show you how to remove and replace your outer HID headlight bulb. This is the high/low on this particular vehicle. This information will be similar for the halogen style headlights. We're doing this particular procedure on the passenger side, but these steps will be the same for the driver's.

Here are the items you'll need for this repair.

This job can easily be done on the ground, but we're going to raise and support our vehicle to make it easier to film and show you what's going on. Turn your wheel in to whatever side you're working on. We're going to be working on the passenger side, so we'll cut our wheel all the way to the left.

Unclip the tabs that secure the floor mat. You only really have to undo these two. Then you can just fold it over and out of the way. This cover is where your battery is located. To get it out more easily, you'll want to lift up and snap this plastic cover off of the seat rail. Remove this T-20 Torx screw here. We're going to do that with a Torx socket, ratchet, and extension. Remove the screw from the cover. Lift the cover up and away. Remove the negative side of the battery with a 10mm socket ratchet and extension. Remove the terminal from the battery and place it out of the way.

Remove the seven T20 Torx screws. We have two on the bottom here and five running up along the backside of the bumper and the fender. Remove the eight plastic clips securing the inner fender well in. We have three in the top area here, one over at the front (in the middle), two down at the bottom, and these two at the back of the front portion of the liner at the bottom in the middle here.

There's a few different ways to remove these style clips. I like to try to take a small flat blade screwdriver and work up the center part of the clip just a little. Once you get it up some, if you have the room to get in there with a pair of side cutters, you can sneak them underneath and then pry up evenly from both sides. Once the center's out, you can pop the lower portion out the same way.

To remove the wheel liner, pull out on the bottom portion here and pull down and forward to release the front half of the wheel well from the rear and sneak it out of the bottom.

The headlight housing can be found up in the top after we've removed the wheel well. This cover, which turns counterclockwise to release is for the outer bulb, which is our high/low HID bulb. Once you've removed that cover, you can remove the bulb with the spring clip. Just be sure that your key is out, and your battery is disconnected before working on this portion of the headlight, as HID bulbs are high voltage.

The spring clip pushes in and then is slid up out of the hook. It will then swing away, and allow us to remove our HID bulb from the assembly. Use a small flat blade screwdriver to lift up on these tabs on either side, and pop the connector up. Do the same thing on the backside. You may have to work them back and forth a couple of times before they pop off and release from the bulb.

Reinstall the connector onto the bulb. Reinstall the bulb into the housing. Always be careful not to touch the glass on the bulbs with your fingers as the oils on your fingers can cause the bulbs to fail prematurely. Swing that latch closed, here. Push down and pull the spring back into its hook. Just give it a quick wiggle to make sure that everything's in there nice and secure. We reinstall our rear cover. Turn it clockwise to lock it back into place.

Reinstall your inner wheel well liner. Do this by pushing it up from the bottom and rotating it in over the tire. Be sure that the top slides into place behind the rear liner, as well as on the sides. Once you have some holes lined up, you can start installing your eight push pins. Set them up like this. Install the bottom half and then pop the tab into place. Reinstall your seven T20 Torx screws. We'll start them a couple of threads by hand before we install them with our socket and ratchet.

Keep your keys handy in case this sets off your vehicle's car alarm, and reconnect the negative side of the battery. Tighten up the 10mm bolt. Reinstall the cover, and tighten down your T20 screw. Put the plastic cover back onto the seat rail. Snap it into place. Lay your floor mat back down. Reengage the hold downs.
