Haven't actually examined the fog lights on the car yet, but one of my lenses is broken. I looked in the haynes manual last night and it has nothing about the fog lights. Is the fog lights a sealed beam unit? And do they come straight out.

You should just be able to pop it out, and get a new lens, or housing, depending on how they did them... my fogs just pop out, then you unscrew the sides, and the whole assembly comes out, where you can then change the bulb, etc..

It should be in the car's manual, if you still have it. If the fog lights have a protective grill, those can be popped out by a screwdriver, allowing you to access the lens housing itself.
