The inside of the lens on my recently purchased 2001 is etched a little. I would like to attempt cleaning it with plastic polish. The previous owner did not have a garage and was not particular, but it bothers me.
It's really on the inside? My headlights are bad too, but on the outside. My sisters boyfriend was kind enough to polish them for me, but they still are all that great. Sorry I can't tell you how to open them, but good luck.
