The OE fog lights are held in by a bolt and a clip behind the bumper cover. Accessing them is easiest when you jack the car up, remove the wheel and tire, and then remove the fender protector (wheel well liner) which is held on by pop-clips and 10mm bolts. Then you can easily access the bolt and clip. The driver side is the easiest, it's wide open. The passenger side is semi-hidden behind the washer fluid reservoir.
Changing the bulbs is pretty easy the "lazy" way (turning then wheel and loosening the fender protector, then just squeezing your arm in). But accessing and removing the whole fog light housing will probably be too hard this way.
Either way make sure you disconnect the negative battery terminal first. This car does not use enough fuses and you can damage the BCM. You don't want that.
