My 99 has always been garaged, until lately. I live in San Diego where it hardly rains and have never noticed moisture inside my headlight lens, until now. The car has been parked in the driveway for several months, we've had some rain and now water has condensed inside the driver-side lens; I can see no leak. I've parked the car in the sunshine and popped the rubber seal off the inside to hopefully let the water evaporate, but to no avail. Although I'm sure I can get the water out, can someone tell me how this likely happened. I have no cracks in the lens and the seals look good. Any ideas would be welcomed.
