I am thinking that you might, might, be able the access the bezel/housing much like you can for changing the light bulb, though the fender/wheel well liner. Start by turning the front of which ever tire inward, unscrew the fender liner retaining screws, peal back the fender liner, an look inside to see what you will need to do to remove it from behind. I'll check my pictures that I have that may lend more insight to how they are mounted in there.
