could somebody please clue me in on how to keep my drivers side headlight corner from fogging up. i caulked it once, didnt work. caulked it twice, didnt work. caulked around the light bulbs, still didnt work. i even took the corner out and sat it on a fan for a day to dry out... twice, still didnt work. why do they do this, and how do i keep them from doing it?!?!!?![]()
