Question about 2003 Chevrolet Cavalier
The cooling fan does not come on at all, used to work
Ok heres a quick common thought of the day....ac triggers fan on ... fan comes on when it need to w/o ac on, so if it came on and shut off when you tapped on the fan, y would you think its a switch obviously the TEMP switch has nothing to do with the fans operation with the ac on... ok here try this, if the fan in your house wouldnt work when you turn it on, you tap on it it spins for a second then shuts back down, would you replace the wall socket? you verified the problem, tapping on the fan made it come on an shut back off so replace the fan ac is obviouosly commanding the fan on if you tapped it and it came on for a brief time, use ur noodle... you *******' that are misleading people who need help should be drug into the road and shot

The fan actually gets a signal from your coolant sensor which is to the left of your engine and has two prongs.
If you remove the sensor connector the fan will most likely come on
the fan is supposed to keep the engine temperature low on a hot day
it works irregardless of wether the ac is working or not.
My advice is to check the resistance of the sensor with a multimeter if it is not within spec then i would change it.
secondly i would replace the relay (becuase it is a cheap part) and there is the possibility that it wont work for the electric radiator fan circuit but it will work for the heater fan circuit you tested it with.
If you have still not found the problem then there is likely to be corrosion from the sensor to the fan or corrossion on the wiring harness from the ecu to the sensor, or ecu to the fan
