2002 Ford Taurus sel with A/C , heater fan works on high only, not on low speeds. 40amp & 3amp fues ok. The heater blower fan only works on high speed. Does not opeerate an the first 3 low speeds. checked the 40 amp blower fuse & it is good. checked 3 amp relay fuse and it is good.

SOURCE: My blower motor fan speed switch will work only on High.

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.

fords are notorius for faulty fan switches, you will need to get a new one, but it will probably fail in a year or two.

There are 4 things to check out to pin point the problem: the switch it's self, the blower relay switch, resistor block, and the blower motor it's self. good luck

Try the autozone.com website and register the car. It doesn't cost anything and you will have access to an online repair manual for the car. The steps doing a brake job should be available there. Hope this helped and best wishes.
