Since it's been raining here the past few days i started to notice that on my moms 2002 camry her passenger side headlight was getting fogged up. I was wondering what was the best way to look for a crack or open seal. The first thing i thought to check was the headlights bulbs were loose but they were all fine I also did a visual inspection of the clear cover but that was fine. Any suggestions on trying to find the leak?
