heater blowing cold air. on 2000 Ford E-150

I have changed the thermostat,heater hoses are hot and in good condition. I have a blend door switch and and a selector switch coming in the mail and the door actuators seem to be working fine. No codes on my scanner. Any suggestions on what I'm missing? Thank you Barry Brown

What engine? Water pump pumping enough volume through heater core? Both hoses burn your hands?
