In the winter in this full size B1500 van when the temp is below freezing all the windows fog up and frost up no matter how much heat the defroster and rear heating vents put out - it gets worse as you drive not better and it feels humid in the vehicle. Has the same problem in the summer only the bi-level A/C setting will eliminate it.

Do you know what the problem is?

Is the AC system working? It should be running when defrost is turned on. That is supposed to remove humidity from the air before blowing it onto the cold windows.
