I don't think it likely but could the heater core be plugged up also? It really isn't that much of a job to remove it and give it a good physcial inspection. If you have owned it a long time and it used to put out heat the way it is, then its a weird one. If this is the case, I would start inspecting everything from the coolant pump to the heater and back. If the engine is cooling properly then the pump is probably OK, barring a clog? No heat in this weather?, I would have torn the whole heater circuit out of there to find the problem. But, you say there is flow but no heat? Is there a thermostat in this engine? that will definitely give you NO heat. Hope all of this helps.

Thanks for the Help and Idea's Boomer...
Just bought the truck less than 60 days ago and It's my 1st Ford (other than my Hot Rod 49' F-1). It's only got 95,000 miles and runs and shifts well. I needed to replace my S-10 when my Nephew Kicked the rods out of it.....
I've been thru everything except tearing out the dash and replacing the Core. I took the Hoses off and ran water thru the core..As soon as I put it in the top (core) hose, it came out the bottom(core) hose clean and clear. I put the thermostat in a pan of boiling water and watched it open and close...It works fine
Temp gauge does not work at all (neither does the gas gauge). I drove it Sunday to work @ 8:00 am and it never warmed the cab up. It drove fine and didn't over heat... Just a Chilly ride.
I don't have a Manual to look over the process of Heater core Removal, but it sounds like it's not too hard. Just not sure where to start tearing things out..
I took out the glove box and saw the Vacume line and vacume diaphram. It moves freely , up and down. I moved the Temp. selector from cold to Hot (ha-ha) and could feel the trap door open and close but no change in cab temp until i put it on the cold side. COLD
I still need to go thru your earlier suggestions to see if anything gets Hot inside the cab....
