Question: Heater Core Freezes Up,
I have a 2001 Dodge 2500 4×4 diesel. My difficulty is the heater center freezes up (visibly frosty beneath the sprint on the passenger facet) and reduces airflow via the ducts to the level that no air is flowing. This transpires when the Air conditioner is on and when the defrost is on. what leads to this?
