I have a 2003 ford Taurus . Automatic V6 flex fuel ses Recently My heat has stopped comming out at full speed. It comes out only when I drive, then I half to be driving for a good while for me to be able to sense with my hand. It barely comes out I've checked fuses. Nothing is blown. Im trying to locate the blower or fan , or whatever part under the hood is responsible for this. If you can help . It would be GREAT APPRECIATED Thanks for reading
