Heater problem
1997 Ford Taurus 6 cyl Front Wheel Drive Automatic

the heater/defrost blows cold air until i take the hose loose on the heater core(return to the thermostat housing) when coolant starts to flow i get good heat. Iput the hose back on and it cools off. The car is not running in a overheat state and i've already replaced the pump, thermostat, heater core, and entire heat box under dash. I've also flushed the coolant system. Any suggestions would really be helpful since i;ve gotten to the end of mine and beating my head against my garage door......thanks
