Most likely the thermostat broke. I expect that you have an older Hyundai and never had the anti-freeze changed. When the engine is cold the thermostat is closed which causes the engine to warm up more quickly. A warm engine runs more efficiently (less gas) and more smoothly. When the engine temp reaches a certain temp the thermostat opens and then allows the hot engine coolant to run through the lines to the heater core. The heater blows air over the heater core which produces the warm air that warms up the cabin. Thermostats used to be cheap and easy to change. I would suggest a web search for how to replace the thermostat. Something like 'hyundai accent 2002 replace thermostat".

Sounds like the problem lies in the thermostat, When the engine thermostat fails to close fully, the engine coolant temperature may fall. Low engine temperature causes several problems and may cause the heater to blow cool air. Make sure about that.

Check your coolant level. May be low. Possible restriction in heater core or radiator. Possible air pocket trapped inside. I believe there is a heater core bypass valve that is actuated electronicly. It may be stuck, causing a restriction. It will be located on one of the coolant hoses coming from the firewall.

Have your thermostat checked, sound like it is not working when cold.

the one thing that comes too mind is trapped air-when i do a radiator I always start up and warm engine so thermostat cycles a few times to make sure that you dont trap air in colling system. you did not say so but if you didnt, its really not a bad idea to change thermostat and gasket when digging into colling system. they are usaully fairly cheap.

Could be thermostat. Even though you had it replaced the recommened temp is 192. You probably have a thermostat with an alternative temp of 160 or 180. This will make your car run alot cooler than it should.

both hoses is hot signifies thatcoolant circulation is just fine check the blend door actuator it might be stuck.pan the heater temp controller from hot to cold do you feel any change in temp of the air from the blower?if you dont feel any change check the blend door actuator

the most probabale cause of this would be a disfunctional hear core if you replace your heater your heater will more than likley work the the way it's supposed to

could be a pluged heater core back flush heater core. or heater controls aren't functioning properly
