The fan motor keeps running when I stop my car and will slow down and speed up but does not turn off. I have to pull the fuse in order to get the fan to stop each time I turn the car off. How hard is this to fix?
Fan motor has a thermal switch which turns on the fan as soon as the engine heats up. what happened there is that the switch is stuck on the closed position which keeps the fan on all the time. you should go to a garrage and have the part changed.

do you mean high engine speed or fan speed. if fan speed is slow then motor in the fan is getting bad. if your talking about running engine, then could be nothing because the sensor tell it not to..like running down the road it cools the car down and engine temp drops slightly enough to cut sensor off.
Sounds like the cooling fan or the circuit is faulty. When you are traveling at highway speeds, it runs fine? But around town it gets hot? If that is correct, it is probably the cooling fan or circuit. Could be a switch or fan motor faulty.
Sometimes this is caused buy a vacuum problem. It is not opening the door to let your air in at a slow speed. The doors are opening at high speed due to the air pressure from the outside air. Make sure that the fan is runnig by turning your ignition on but not starting the engine. Turn the fan on high and see if you can hear it. If the fan is running then take you car to a mechanic you trust and have them check the vacuum going to the door.
It could be caused by the fan bearings failing (normally sleeve types that get gummy), switch failing (does speed setting make any difference?) or finally connector problems caused by corrosion.
If the speed selection resistor was failing, it would affect lower speeds but not the highest speed since it is then bypassed.
Operating the switch that selects fan speed rather roughly could clean the contacts in the switch and help cure the problem if the switch is at fault.
If the fan motor slows down regardless of speed setting, it is likely the motor (bearings) at fault which would likely require replacement of the fan.
Access to the fan may be a real pain-in-the-. . . well, you know.
I don't have my manual with me but that is a self-set speed warning. Essentially, you can set an "alarm" to go on when your car reaches a set speed...to alert yourself that you should slow down. To reset the speed alarm, go to the desired speed and hold down the "check" button. Otherwise, just look it up in your manual. It's fairly easy to fix....
Most likely it does, if you can hit the motor and it will run. I can't say for sure but you might want to chk. to see if you got a heater blower motor resister. There located (if its got one) around the heater motor and it controls blower speeds, might be worth checking out.
