Re: 2002 Ford Taurus blower fan only works on high
Do a little research you will find that the 2002 Ford Taurus was notorious for a faulty cabin filter that leaked water into the motor..the first thing to go is the resistor which will only allow the fan to work on high. Eventually the motor will go altogether. Two things need to be done after that, R/R the motor then reseal the cabin filter if your car has one..also Ford has a Rain Hat that they will gladly charge you around $200 bucks to install if you want to try that option
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Does it work on any speed..If not check the relay..If it works on high only,,its the fan resister..If all fails you have to unhook the the fan wire and check for voltage with a test light or multimeter..If you have voltage then the motor is bad
Usually when the blower fan only operates on hi speed, its because of a failed blower motor resistor. You still have hi speed because on hi, the power going to the blower motor goes directly to it, as opposed to the lower speeds, when the power is routed through the resistor, thus lowering the voltage, which in turn lowers the speed of the fan. The resistor is usually located near the blower motor itself, under the hood back near the firewall.
I had a similar problem with my 03 Taurus. Does your floorboard on the passenger side get wet when it rains really hard? If so, Ford is aware of a defect above the fan motor which is behind the glovebox.
I contacted Ford directly and they had my local ford dealer fix it free and they gave me money towards a new blower motor which shorted out from the leak, it's possible it just your switch if there is no leak but you might need both the switch and blower motor replaced like I did. Hope this helps.
This is a pretty common complaint and is almost certainly due to a failed heater fan resistor.
This is a stepped resistor with taps that set the different speeds on your blower and if any part of it goes bad, the whole thing doesn't work any more and the highest speed is the only one that bypasses this part.
These are often mounted on the fire wall but may not be exposed so you really need a service manual (Haynes or Chilton will do) to locate it in your car.
Ignition switch is the culprit. On Fords for high speed blower motor is direct whereas the lower speeds go through the ignition switch. If there is an issue with the switch the blower will only work at high speed. A schematic will confirm that.
