This is about 2003 Corolla. No problems before this, this is a new thing and only in one headlight. I removed all bulbs and dried it very well inside by blowing hair dryer into one of bulb holes. There are no cracks or holes that I can see and the rubber gaskets on bulbs are in good shape and installed correctly. I even used silicon grease to increase sealing at the gaskets when reinserting the bulbs. It was great for a full day and I washed the car and dried it in a shade and no water leaks and no fog inside. I congratulated myself for the easy fix only to find the next morning fog inside again. The nights are chilly now and there is condensation on the car when you keep it outdoor overnight. What is going on? How does it go inside the headlights? Anyone please?
