I don't believe it is a blown heater core as there are no leaks in or outside the truck.

Hello, It sounds like you may be correct in that you have a leaking heater core causing the windows to fog up as a result of the excess moisture inside the cab. I would recommend having a professional from YoruMechanic come to your location to diagnose and inspect your heater.
