Engine Cooling problem
1998 Pontiac Sunfire 4 cyl Two Wheel Drive Automatic

Cooling fan will not come on when air turned on or when reaches temp when it should come on. I put power to fan it works , changed the relay with a good on and checked power to relay and to fuses and checked fuses all good checked sending unit ohmed cool and hot checks out good. Could it be the control module? I still not to check wires

Your talking about the radiator fan? If you unplug the coolant temp sensor, turn the key to on, does the fan run? I'd have to check voltage and ground circuit at the fan relay. Any applicable trouble codes?
