....Well... as I have just found out.......you have to pull apart the whole dash... unscrew the steering wheel from the frame... take out the frame underneath the dash.... and then unscrew the heater side of the heater/ A/C unit. Then it comes out pretty easily. I just did it and it took me about an hour. The problem I have now is that I need to find a heater core... which has been a problem. I'm hoping that I can find one at the junk yard that will fit in my car...... and isn't damaged. I hope that helped.
You may need to replace your Thermostat or your Heater Core.
The heater core in a 2000 Kia Sephia is located inside the vehicle's dashboard, typically on the passenger side. To access it, you generally need to remove the dashboard and possibly the center console, as it is integrated into the heating and cooling system of the car. It's advisable to refer to a repair manual for detailed steps and safety precautions when attempting to reach or replace the heater core.

you can try radiator leak stopper, but i would just replace heater core .,eally cannot be repaired.
To replace the heater core in a 2003 Kia Sorento, start by disconnecting the negative battery cable and draining the coolant from the radiator. Remove the dashboard and center console to access the heater core, then disconnect the hoses connected to it. Replace the old heater core with the new one, reconnect the hoses, and reassemble the dashboard. Finally, refill the cooling system with coolant and check for leaks before reconnecting the battery.
MAKE sure that is the problem.If heater is blowing cold air,reach on passenger side,under dash,and find the heater blower,and gently pull the white plastic piece to make sure it is not stuck on cold.They go from hot to cold easily but not back to heat.
