Things to check. Is the radiator full? Are the hoses connected to the heator core at the firewall? All vacumn lines connected. When engine warm, feel both heater hoses to see if water is circulating thru the heater core. If you think the heater core is pluged, remove both hoses from the core and try blowing air or water thru it. This will show if it is plugged or not and may point you to the cause. Fill the radiator with the car running as this is the only way to insure the cooling system is full and circulating.
In most cases when a vehicle heater that has been working properly in the past begins to blow cold air the cooling system is low on coolant. It could also mean that your heater core is clogged. A good coolant system flush might take care of this, otherwise you may have to have it replaced.
