One possibility is that your thermostat is stuck in the open position. It is only supposed to open (or let coolant flow through the radiator) when the coolant is at about 200 degrees Fahrenheit. If it is stuck in the open position the coolant doesn't get the opportunity to absorb the heat from the engine and transfer it to the radiator or the heater core. (This is a possibility)

A heater in a 2002 Honda Civic EX may blow cold air at idle or while stopped due to a few potential issues. One common cause is low coolant levels, which can prevent proper circulation through the heater core. Another possibility is a malfunctioning thermostat that might not be opening properly, leading to insufficient engine temperature. Additionally, a failing water pump or air trapped in the cooling system can also disrupt the flow of hot coolant to the heater core.
