Cooling fan I own a '96 Ford Taurus and the cooling fan will not shut off. Even when the ignition is in the off position.

There are 2 relays for the cooling fans. They are located in the power distribution box located in the engine compartment (see picture below of location). there is a low speed fan relay located in the number 24 position and a high speed fan relay located in the number 32 position (see layout picture below). If your fans are not working at all you may also want to look at the "maxi" fuse in the number 9 position as that gives power to those relays. i hope this helps and good luck.

That's because you have to reporgram the new key to your computer. There is a chip in the key.

some do that but if it runs after the car is cold then you have a bad relay

Cooling fans only run when the temp,of the coolant get to about 215 to 218 degrees,and shut them selves off,when the engine cools down,if they do not cut off,the engine is not cooling down,now,if the ac is on,the cooling fans will stay on until the ac is shut off.

You may ahve a bad engine coolant temp sensor. If it goes, the cooling fans default to always on high speed.

It is the cooling fan relay,it will be in the fuse/relay box under the hood,on drivers side,or near the fans,if you remove the correct relay,the cooling fans will turn off.Just replace it with a new one from the parts store.

the thermostat can be easily changed from up top, the T-stat is located at the engine end of the upper radiator hose under the flange the hose connects to. Make sure u follow manufacturer's cooling system bleeding procedures when you refill after the T-stat is changed out.

When this happens, leave the key in the ignition and change from park to neutral and back again. I have to do this on my Taurus SHO from time to time. It won't start because it doesn't think it is in Park. Something to do with the shift selector switch on the transmission.

It is my guess you have a defective ignition switch.

You need to replace the ignition lock cylinder and/or the ignition switch actuator parts that turn the electrical switch off,on,start when the key is turned, the electrical part of the ignition is remote from the lock cylinder, it is operated by a gears and a rod.
