John,

Sounds like you hit all the easy stuff.

You don't say what year taurus you have. 

Anyway, follow the heater hoses and see if you don't have a heater control 
valve.  If you do, it should should be in the supply line to the heater.  
It will probably have a vac. line going to it.  Most are sort of conical.

If you have one, check to see if you have vac. at that line and in what
positions of the heater control.  Some of them are opened by vac. some are
closed by vac.  

If you have vac. then and can make it come and go, based on max heat 
(recirculate) and then heat, chances are that that valve has died.

If you don't have vac. there, then you either have a vac. leak, or the
control switch (can be either on the heater box itself, or on the heater
control module) is not working.
