I recently noticed after detailing my car, that the headlamps were dirty(foggy) from the inside. I noticed this while my car was dirty but figured it was just dirt on the outside of the housing. It doesn't look like it is from moisture getting inside, it just looks like dust, hence the foggy appearance. When i got the car in Dec. the lights were crystal clear, now they look old and dusty. Anyone else have this problem, and if so how did you fix it? My car is still under factory warranty. Does anyone think Cadillac would replace the headlamp housing because of this? Or, am I screwed because technically nothing is wrong with the housing. Thanks in advance.
