Where Is The Cooling Fan Relay Located In A 1994 Chevy Corsica, V6, 3.1L

Posted in Engine & DriveTrain

My cooling fan is not working. I replaced the coolant temperature sensor but with no luck. When I unplug the sensor and I start the engine the fan kicks in, but the Service Engine Soon light is on. Could it be the relay? How do I find it. This car is unbelievable. It doesn’ t have a relay block. Please help!!!!!
I couldn’t say it’s overheating. It only goes a bit beyond the half line, but shouldn’t the fan still kick in. I’m worried about the summer when it’s gona be really hot here in AZ.

      If you unplug the sensor and the fan comes on, the relay is working. What makes you think you have a problem. Is the car overheating?

      Your cooling fan will not come on till it reaches about 228 degrees. It should come on all the time if the a/c is on.
      Sounds normal to me.

      that senser you unpluged and fan came on, says the fan is ok.
      the senser it’s self is bad, if it does not trip the cooling fan. If it is any thing like my Olds Cyttlas Supreme with the 3.1l V-6, you have two fans behind the raidaitor. Yes, unplugging it with engine running, will trip the engine light also
