    if you aren't talking about VACUUM THERMAL SWITCH, i think this steps will help u a lot. first you can try checking connections to the radiator fans usually they get toasted cause of the currrent flow. if you notice, turn ignition key on do not crank the engine, you should have a quick on an off power to your fan. if it dont happen, warm up engine to normal temperature, and disconnect your engine coolant temperature sensor, that will trigger the fans on. if it dont happen your problem could be at te constant relay control module. mrfordman said. i would like help u and get it fixed.

1993 ford taurus will not come out of park, brake lights won't come on even with new fuse

You likely have a broken wiring harness at the brake light switch connector under the dash above the brake pedal. You can buy a replacement stub harness from Ford parts.

I have a 1994 ford taurus station wagon, the battery won't stay charged, the confusing thing is that the inside panel and door light works

you have a faulty alternator by the sounds of it, try this simple test, : test the voltage of the battery with the vehicle off with a simple multimeter, it should read just over 12v then test it with the car running, it should read around 14-14.5 volts if it still only reads 12v then your alternator needs replacing.

1991 ford taurus still overheats after replacing,thremostat,radiator,hoses\r\ni think the fan is not coming on when it should .

If the primary cooling fan is electric, it will be controlled by a primitive thermal switch located in the rear of the bottom radiator tank,
If it has two wires, disconnect them from the switch and, with the ignition on, short the incoming leads briefly together with a paper clip or short piece of copper wire; if the fan kicks off, the fan is OK and the switch is bad.
If only one lead, disconnect it and again with the ignition on, ground it to a clean metal chassis point; this should turn the fan on. If the fan starts, then the switch is bad.

I dont have much heat in my 2001 ford taurus, can u help?i have replaced thermostat,checked for plugged heater core, and lines,coolant levels checked,not sure what to do next.

The electric cooling fan could be running all the time, or at least running more that it should, thereby not letting the engine reach normal temperature. There is a thermal switch that tells the fan when to come on. It is probably bad.

Air continues to run with engine off

The air conditioner compressor is driven via belt by the engine; if the engine is off, the compressor is off = no AC.

You didn't mention which fan is still running but I'll assume it is the one underthe hood, not the one that circulates passenger compartment air. 
What is running is the electric fan that assists with cooling of the heat exchanger of the AC system. You probably have a thermal switch or relay that is not releasing.

Locate the relay/fuse box and check if there is a chart of the relays and fuses to locate the one that isn't releasing and try swapping two relays with the same part number on them to check relay function.
