Hi @pontiacuser2000 ,
 
It may be that the radiator core is partially blocked and needs to be flushed
 
Have you scanned the OBDII port to see if there are any 'codes' giving an indication of a problem?
 
There is a coolant temp sensor that sends the temp reading (actually a resistance value that changes with temp) to the ECU and at a programmed 'temp' setting the ECU operates the fan relay(s) which turn on the fans The number of relays it operates depends on the fan speed required and whether or not the A/C is operating.
 
Suggest that you may wish to check if the sensor is OK. I think that the temp sensor is located where the upper hose goes into the engine but not entirely sure of this
 
There are 4 relays in the engine fuse block for the fans according to this [http://www.autogenius.info/pontiac-grand-am-2000-fuse-box-diagram/|link] (Scroll down to engine block fuse panelpanel. Relays 8, 12, 14, 15)

If the temp sensor is OK check if the relay is operating. If not try another relay or check the relay's operate path.

If the temp sensor is OK check if the relay is operating. If not try another relay or check the relay's operate path. Perhaps the wiring is corroded from the ECU etc.
