Since you have already tested fan and relay and both work, the problem may be the engine temp sensor. There are two sensors. One goes to instument cluster. This is engine coolant temp sensor, the other is engine temp sensor which is usually attached to engine block, sometimes they are connected to thermostat housing with the coolant sensor. You can pully the engine temp sensor and test that sensor same way as relay. (with mulitimeter)

Have a 2002 cavalier Z24 and the cooling fan will not go on. Have a hard code on the engine saying Cooling Fan 1 Control Circuit. checked all the fuses and the relay, all are fine. what might the problem...


there are two coolant temp sensors on this car one controls the fans and one controls the temp guage in the car. one is located near the thermostat housing and the other is usually located in the block. the one near the thermostat housing usually controls the fans. also try to jumper the fan and make sure the fan is working.

Cooling fan won't come on, have tested fan and replaced temperature sensor.


First question to you is.. Have you checked the wiring or ECU codes?




check the cooling fan switch on the back of the block, unplug the connector and jumper.
2 wires, turn ignition on and fan should come on...

if it does-----replace the cooling fan switch
if it doesnt----- go to the cooling fan relay on the pass side inner fender
panel behind the headlight and check it, besides the fan itself and the fuse, those are the only things in the system.
