I bought my fully loaded Laramie 5th gen in Sept 2018. After 42,000 miles, I now have a serious issue of water collecting in what seems to be my ducting behind my dash board. When I drive the truck, the water pours out of my cabin air filter housing. It's a nightmare. I drive around with the cabin air filter out and let the water slowly drain. It seems like there is a gutter clogged in my cowling. The water slowly drips out from my passenger side quarter panel behind the wheel well. Of course the dealer zombies had no idea how to fix it. I tried looking and cleaning (it's never dirty). Does anyone know the location of the cowl drain?? Oh and yes, I too am starting to get the leak above the back power window. Frustrating that the best truck I ever owned is turning into a POS.
