Heater sucks!!! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It has been getting pretty cold around here lately, the last couple days the high temp has gotten clear into the low 20s. My heater seemed like it worked fine in the fall but as I was driving on the freeway in some thick fog it was freezing to the windshield and the defrost vents felt like they were blowing out 60 degree air. I was still pretty chilly despite having an arctic carhartt jacket on.

I would not think the cold air would keep the coolant THAT cold, does this sound more like a nearly plugged up heater core?
