The heat works because it extracts heat from the engine coolant fluid using a small radiator-like device located behind the dashboard called a heater core. Now there is obviously air in the heater core or there is simply no coolant in the engine at all. Check the coolant level and add some until it is full. Do you know how to purge air from the cooling system? I can tell you how if you don't.

Most cars will bleed themselves while filling if you fill it slowly.. Or while driving, the radiator cap will release the air but there could be air getting in from a small leak somewhere in the cooling system or even worse, head gaskets... First check underneath the car after it has been sitting for a while and see if there is any coolant that has leaked onto the ground underneath the car. If not, check the oil. If you can smell coolant or see it in there, you probably have bad head gaskets and that is why you have air in the cooling system... Lets just assume that you don't have any of these problems though, and just want to bleed the air from your cooling system! The best thing to do is park the car nose up on a hill or use a floor jack and raise the front end a little. Then fill slowly and let the coolant work its way into the bottom of the engine and force air out the top. When it gets high enough to see it, crank the engine and wait till it warms up and starts circulating. Slowly finish filling completely and install the cap. Fill the reservoir to the full line. Drive it around a bit, turn on the heater for a minute and make sure it is blowing hot air. Stop it and let it cool and check the level.
