Question about Cars & Trucks
Sometimes these fans are made to run after the engine is shut off to dissipate residual heat. Will it shut off after 5 minutes on its own? If it continues to run after several minutes, then you need a new thermal switch in the radiator.

Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson

There's a thermostatic switch that kicks the fan on and off. It is apparently shorted, causing the fan to run continuously. Check with your local auto parts store -- you be able to replace the switch without having to replace the entire fan assembly. In the meantime, pulling the fuse is a lot better than disconnecting the battery. You won't lose computer memory, clock, stereo memory, etc.
