The part that transfers heat into the passenger compartment is called a heater core.;A heater core can be thought of as a miniature radiator. The car engine's coolant flows through the heater core while the fan (also called;a blower), blows air;through the heater core fins. As we already said coolant is what warms the heater core. If only one is hot, this indicates there is is a blockage in the heater core or there is air trapped in the;heater core. If;the coolant is really brown, has been neglected, or;if "stop leak" has been used at some;point,;the heater core could be stopped up. Check for presence of a heater control valve by following the heater hoses back to the engine. When a heater core leaks, usually they wet the passenger side floorboard. The labor cost to change heater cores;is usually expensive, so sometimes people will loop;the heater hoses;and by-pass;a leaking heater core instead of repairing it properly.

f the door;is not operating, find the door that;controls the airflow;across the heater core. If the vacuum;motor does not hold vacuum, the diaphragm is leaking requiring;replacement.
