Auto Air Conditioning & Heater Repair: Heater not working, blower works, ford taurus

Question
The car engine gets hot and the blower works, but the air is not coming thru the vents and therefore the car is not heating. Could it possibly be stopped up or is it a switch thats malfunctioning. Someone told me is could be the thermostat.  Could you please give me some ideas.
Thanks  My car is a 1999 Ford Taurus  303 engine, I think.

I had my radiator recently flushed in case that could have something to do with it.

Answer
You ALWAYS replace the thermostat and any hoses that appear bulged or worn when you flush a radiator.


Are both heater hoses hot to the touch ?.

Are you getting col or warm or hot air into the passengers compartment ?.

What vents is the air coming out of ?.
