I noticed on my truck a few small "runs?" of water going down the rear window, and unfortunately, a few on the front windshield as well. They looked like water had ran down and had left a path so to speak on the inside of the glass. This has never happened before. It was a very humid hot and rainy day, and I kinda hoped it was just condesation or something that had beeded up and ran down. I will definitely take the tail light off now like mentioned, but I'm not sure about the front....
