Although my car is not an Eclipse, I experienced the same issue. A mechanic determined that my radiator was partially blocked and recommended replacement. My heater now blows heat whether I'm stopped at a light or moving.
The most common reason a automobile heater blows cold air is the water level is low. Check the water level and fill to the appropriate level.
Your heater will blow cold air only.
the heater blows warm air when fan is on low but blows cold air when fan is turn to higher setting
you must have low coolant or a bad heater core
