Yeah man i had the same problem and i just took it to the dealer and they fixed it.
Yeah the dealer just replaced it with a headlight that had the correct sealant in it. Replacement headlights from the dealer on the 2000-2002 LS's are replaced with the newer style headlights that have a "black" glue unlike that of the previous years. Those headlights had a "grey" glue and was susceptible to breaking down due to the heat the headlight and engine compartment generated. If your car is out of warranty you can fix the headlight yourself and save a ton of money.
1. Take out headlight and bulbs
2. Pre-heat oven to 250 degrees
3. Take three metal clips off bottom of headlight
4. Place headlight in oven for 5-7 minutes
5. Using leather gloves take headlight out of oven and press around the headlight that meets the clear part. You should hear "squishing" of the grey glue which means you are spreading the glue around insided the joined areas.
6. After the headlight cools down, take some high-heat black RTV silicone and place a bead all around the headlight where the black and clear parts of the headlight meet.
7. Spread the silicone around the seam with your finger to "work in" the silicone in the seam.
8. Allow silicone to dry according to the directions and replace headlight
This should solve about 99% of your problem. If the fogging continues this means you have a small hole or opening in the body of the headlight. Also, remember that you can not do this procedure with any headlight that has the "black" glue.
Hope this helps!
