2005 Mercury Mariner Question: How do I change foglights on this vehicle?
Answer #1Visitor, January 20, 2011, 12:13
i just put HID in the fogs, had to pull the tire off and take the inner wheel well (splash guard) half way off or just enough to bend it out the way and right there inside the lower bumper there is the back of the bulb and they have 2 clips if you had to take the complete fog light housing out.
