1998 V6 Taurus No heat!!!! What could it be???

I have no heat...it blows warm air for 3 seconds and then is cold. I have checked the blower motor, replaced the thermostat, car heats up to normal operating temperature, replaced the water pump, thoroughly flushed including back flushing the heater core...all debris and little rust were cleaned out...no clogs...could it be the blend actuator door??? Yet I can hear it move...maybe it's not opening all the way??? Could it be my cooling temperature sensor??? Any ideas are greatly appreciated!!

If the heat is there for a few seconds and then is gone, you almost certainly have a clogged heater core. If you leave the blower off it will eventually heat up, but as soon as you turn it on all the heat is taken and since the core isn't flowing, it's not being replaced. It still might be 80% clogged and all the flow in in the 20% that isn't clogged. I would try soaking the core with CLR for about an hour and then repeating the flush. Try compressed air too if you have it. If that doesn't work you might have to just replace the core.
