What would be some ideas of why I have no heat. The fan motor works and there is plenty of anti freeze. I replaced the thermostat but that didn't fix it either.

Your heater core is most likely the problem. Good luck

Check under the dash and make sure all the heating control linkage is connected up to the dampers on the heater box.

Look in the engine bay for a black vaccuum ball with a rubber line coming out of the bottom of it (Pass Side). It should have a vaccuum line going to the intake behind the carb/tbi. You may not have vaccuum to open and close the flaps. Line may have a crack in it.
