WHAT CAUSES THE HEATER TO BLOW COLD AIR?

2001 Kia Optima

Have no heat. The heater blows cold, have changed the thermostat and still blows cold. The top heater coil hose is hot, the bottom one is cold. I believe there is a blockage. Can anyone help me?

Sounds like the heater core is blocked I would start by seeing if its clogged.
