Question about 1995 Buick Century
There is a realay located on the radiator that makes the fan come on. Locate it by the front passenger corner of the hood. Then I would find the temperature sensors that control the fan (usually one for switching on temp, and another for shutting off temp).
Replacement of one or both of these will solve the problem. There is a test procedure for these. Pull these relays attach a meter to the terminals and measure resitance. Place them in a pan with hot water and see if your reading change. If they do not it is bad. Good Luck

The cause of this problem is the blower speed control resistor is shorted, it is very common, there is a GM service repair bulletin on it. to replace the blower speed regulator resistor go the firewall in the engine compartment, the speed controller has a four wire connector to it, it is held into the air ducting of the system by two machine screws.
here is a Photo and part number with price.
