No your thermostat is stuck open which will not hurt the engine. but needs to be replaced, the thermostat is what allows the engine get up to operating temp. before allowing water to flow through the radiator and when it is stuck open it doesnt allow the engine to reach operating temp. so the heater never gets hot. I hope that helps you out.

I would first check to see if both heater hoses are hot to the heater.
if 1 is hot and 1 is cold the heater control valve is closed or the heater core is plugged.

try changing the thermostat if thats not it check and see if you have water leaking in the passenger side floor board if so then you need a new heater core

SOURCE: Heater blows cold air.
heater cores clog in taurus. way to know is this--engine fully hot--heat on reach down to the fire wall and grab hold of one of the heater hoses where it hooks to the core--one should be real hard to keep hold of because its that hot. If the other is close to the same the core is not clogged. But if the other is cold to the touch its clogged. You can remove the hoses and shoot garden hose water in one side or the other and break it loose usually
