Problem is most likely the water pump.Have seen several of these doing this on the 5.4L. Impeller fins were damaged on the ones that I have seen.
SOURCE: Radiator blockage?
I believe you have a head gasket blown or a cracked head. When you start it up COLD with the cap off, it would push water out immediately. Fill it with plain water and try this. It might not be a bad idea to perform a pressure test too. Also check for antifreeze in the oil. It will get milky looking and might even be over full. If this happens after warm-up, you may just have a plugged radiator. Have it professionally cleaned. The water pump vanes could also possibly be corroded off and it's not effectively displacing coolant. Hope this helps.

This is a common problem, Ford garage will charge you about 1000.00 to fix it. It's an all day job for someone who knows what they're doing. I wouldn't recommend this if you aren't familiar with cars. If you still want to go at it, get a book for your car, you will like that much better. It has pictures!

Is the blower motor working? If not that is what it is. If it is working then check heater coil out, Could be bad heater coil.
SOURCE: heater blows cold
If no coolant flowing through the heater core then ther is no heat. There are 2 possible root causes needed to check out: 1- THE VALVE TO CONTROL THE COOLANT FLOWING TO THE HEATER CORE IS NOT OPENING AS DESIRED. 2- THE HEATER CORE GOT CLOGGED UP AND NEED TO BE FLUSHED.
