Apparently no blown fuses. Switched relays. Replaced the fan resistor assembly.
Have you checked the switch?
There are two fuses for the blower. One for the relay coil and the other for the relay power. One is a 5a in the interior fuse box. The other is a 40a in the engine compartment fuse box.
Checked the fan blower switch? Start by checking for 12V at the fan, and work backwards from there until you find 12V, when you do the circuit is broken between the las 2 points you checked. Also make sure the blower, etc., had good clean grounds.
SOURCE: heater fan not working
my car is Isuzu rodeo, this morning found the blower of heater not turning no heater work.
SOURCE: I've replaced the cooling fan motor on my 2003
Remove the fan from the motor to see if the noise stops. If the motor is still noisy, take it back to wherever you bought it for another unit. Sometimes, the rotor of the motor moves end-wise during running under power and cause interference with the fan.
The temperature sensor near the thermostat may be malfunctioning and not turning the fan on (through the computer) when the temperature comes up to normal.

I just changed the resistor on a 2000 F-150 hopefully it's in the same spot. It's under the dash on the passenger side it toward the front of the truck from the glove compartment. I had to use a mirror to see it but, I'm a big guy and I'm getting old so I can't get into those tight spots anymore. But, that's the problem if you only have "high". Merry Chrsitmas!

look under the dash for a big black box the fan will be in that box but first check the wires for good connections and power
SOURCE: Heater /cooling fan will not work first 2 speeds
You DO have a resistor--I think I see it next to the blower in the pic below. I marked it on the pic. You may want to go ahead and replace both the resistor AND the switch as they are cheap for the Taurus. You'll be able to tell right away if the resistor is bad--it will look burned. To get to the resistor, just remove the insulating panel under the dash on the passenger's side. You will see the motor up there and all the wiring.
To get to the switch, you have to remove the whole radio/climate control using special prongs. They sell these at the parts stores by the aftermarket stereos, but I always just make them out of a coat hanger. You push them in about and inch and pry outward while pulling the radio out--see pic and let me know if you have questions.
