When i first beging driving all seem ok air moves truck get nice and warm and all is good. after 30 minutes or so the blower still blowing but no air is coming out. I have checked all things i can think of. The antifreeze is full, heater hoses are hot. controls appear to be working. Is there anything else i can look at to correct this
What all have you checked? It could be a couple of things. You could have a bit of a vacuum leak preventing the blender door from moving, or the door could be not working right. You could have a blockage in your fan duct.
