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 Thanks.

In this video, we're going to show you how to replace the third brake light on this 2003 Mercury Mountaineer. It's the same part and similar process on these Mountaineers from 2002 to 2010. The items you'll need for this are a new third brake light from and a Philips screwdriver.

Your third brake light is held on with two Philips screws. Just go ahead and remove those. Then, just pull the third brake light back and out, and pull your washer hose free. Then push the tab on this harness, and disconnect it.

On the bottom, is the old third brake light. Above it is the new one from 1A Auto. You can see they're identical and will fit exactly the same. The end of this is dry and formed, and widened out, so I'm afraid it might leak. I'm just going to snip off the end. Replace those two Philips screws and tighten them up. Just test out the third brake light. You can see it works, so you're all set.
