I read a post about the third brake light leaking water. Did a search and got 11 pages of lots of info, but could not find the one concerning this. I have a small amount of water under the rear seat on the drivers side after a rain or going through the car wash. I can't find any water coming under the rear window. How would you suggest I reseal around the brake light. Hesitate taking it to the dealer, probably have more problems than I have now!! Thanks for any advice.
