I have a fog light that doesn't work, I tried to access it but its very dificult (the screws are small and the space too). Any help?

 

Unbolt the bracket that holds the whole assembly on, then you can get to everything.

 

There are just two 10mm bolts and a plug (per side) that you have to remove and then you can take the whole assembly out. After that, there are two screws holding the glass part in. I think it took me about 10-15 minutes to change both bulbs out and I am pretty slow.

You probably just have a burned out bulb or possibly your connection came loose or was damaged. Just be sure not to touch any bulbs with your fingers...
