How do you go about changing the fog light assembly? The glass is broken on mine?

 

Take off the bumper and remove and reinstall it

 

You can get to the passenger side one from the wheel well but it's not a pleasant experience.

The easiest/best/right way is to pull the bumper. Which isn't too difficult.

 

You can access both sides fairly easily through the fender lining......I’ve had to replace both mine over time due to rocks.....there are 3 screws that hold the whole housing from behind the bumper. A long shank Phillips head screw driver makes it much easier.....It literally took me less than 30 mins either side, not having to remove the bumper......
