How to fix Fan speed control knob; The Ford Taurs 2001 Fan speed control knob just went bad yesterday. The A/C or Fan only works if i turn the dial to its max speed, but none of its previous speed setting works now. I talked to a mechanic nearby, he said that happened to Ford Taurus on serveal of his customers. He said probably i need to get a new panel from Ford dealer, Any suggestion?

I disagree. The most common thing to cause a blower motor to not work on high is the blower motor resistor block. There is a plastic cover under the R. side of the dash. remove it and you will find the resistor on the A/C box next to the blower motor. It has 4 wires going to it.

Thank you, I look for the resistor under the R.side of dash, and here what i found,

Im not sure which one is the resistor that i need to change? Can you take a look on these two photos, and give me some more instruction, thank you.

That black plastic thing is the A/C box. That connector that made an air rushing sound when disconnected is the vacuum system that operates the A/C mode doors, the only exception being the temp. blend door, which is an electric actuator (motor). Plug this back in. Move more to the R. side of the car under the dash and look up. It has 4 wires going to it. They are not 4 in a row, they are 2 by 2. It's held in by 2 screws. It's right next to the blower motor, which has 2 wires going to it. It is on the bottom of the black box.

Thank you for your quick reply; before starting my 4months out of town work, i took these photos(one of them is not so clear), sorry for the late response and hope you can take a look on them.

See the attached pictures. Circled in red is the resistor block.

Thank you, where can i get a replacement of this blower resistor block?

I searched several sites for this item with no luck, I'm guessing it's a dealer only part but I may be wrong.

Need advice again,
My wife sent the Taurus for resistor block replacement, and it did work on the way home, but after sitting in garage for 3 days it failed again at the engine start. So she sent it back to fix again, and they replaced one of the resistor, although this time it worked for 2 more days but failed again. She noted that blower fail to work happened at the time when she started the engine. Any idea?

Don't remember if they still have this feature but there used to be a thing where when the engine was cold a switch on the heater tubes would keep the blower from working until the engine was warm enough. I'll have to look it up later. Come back around 7 PMish...
