1997 Saturn SL2 my cooling fan wont turn on

Power the fan from the battery if it turns on check and test the fan relay-

If ur cooling fan comes on with the a/c but not when ur car gets to 222-226 degrees then I would replace the coolant temp sensor it's screwed into the head below where the upper hose attaches. There's two wires going to it a yellow one and black one. Also check the connector if it's corroded then replace the connector as well. Make sure u get a brass tipped the plastic tipped ones crack. Make sure the engine is cold and u will loose some coolant. Let me know how it goes.
