Question about 2004 Kia Sedona
Check the heater hoses going into the firewall when hot they should both be warm one more so than the other. if they are cool you do not have coolant geting to the heater core thermostat is wrong or backwards. I asume you replaced the stat due to this problem so your hoses are probably hot. If there is a big differance the heater core may be plugged. flush it from the cooler of the two hoses with a garden hose out the side of the hotter hose. DO not do this while it is hot! If the hoses are close in temp you have a blend door control issue. It may be the actuator on the heater box or the controller on the dash. Good Luck
