The fog lights are a pain to reach as you have to remove the splash guards underneath the engine to reach them. Once you remove the guards you can reach in to either change the bulbs or remove the whole unit. I found that if you remove the unit, three bolts, its much easier to change the bulbs and clean the unit itself. Not sure about the fuse, probably in the manual, but look to see if the fuse is broken first, then if its not, look to see if the bulb is busted. After all that is done just buy any regular bulb thats specific to the fog lights and you are good.
