SOURCE: Heater/AC Fan does not work in our 1998 Buick Century

Fan will be under dash on passengers side , Removing glove box might be needed, Gm also uses a blower resister ro control fan speeds. First check your fuse and then check and make sure your getting 12 volts to the terminal at the blower, You could have a blown fuse, a bad switch, or a bad resister , if your getting voltage to blower motor then most likely it will be the motor. These are not to difficult to change. I hope this helps, please be aware I can only guess at what the problem is from my past experience.

SOURCE: Cooling fan not activating

On most vehicles, there is a thermostatic switch located on the bottom tank of the radiator that controls the electric fan. When AC is turned on, this switch is bypassed so its failure is 'cured.' These switches aren't terribly expensive nor difficult to replace but ensure you don't lose coolant on the ground while replacing the switch since the stuff is tasty and toxic to animals.
If you like to be able to research and or repair minor problems like this, you might consider buying the Haynes manual for your car. This will also let you approximately access what a repair might cost for labor if you can see the degree of difficulty yourself.

89 buick century idling ruff when started, and fan comes on right away even though car is cool, but drive ok ones you get going? Ive got a code 22/ 42 Thanks so much

You need to determine why the fan is on (stuck relay, bad sensor etc.) If it remains on, the computer keeps engine controls in "cold-start" mode and will not operate properly. (re-check codes after the fan works right.)
