F you have battery power and ignition power at the relay, and the circuit is good from the relay to the fan. then the fan is turned on bt the high pressure A/C switch or the ECU. If the circuit (ground ) to the ECU is good you probably have a bad ECU.

Fan quit working


electric fans have a few components . a fan relay usually in a cluster under the hood, temp sensor usually in the engine close to the thermostat , and the fan itself. any of these could cause the fan to stop working. most common is the fan relay . simple fix just unplug and replace. I would first check the fan to see if it runs when hot wired. simply unplug the wires and test the fan with jumper wires from the battery to see if the fans do run. if it fails replace it , the temp sensor is the most complex as it requires replacing by draining the water , removing and replacing ,be sure to use tethelon tape on the threads of the new sensor or it will leak. replace the antifreeze and make sure the system is filled completely. cycle the cooling system 5 -6 times to make sure all air is purged from system or other issues will arise.

Radiator fan runs constantly... yet temp. is normal


replace the fan relay because if the points are stuck , the fan will be getting power all the time
easy check when the fan is running , pull the relay and the fan will stop
put it back in and if the fan starts up again , it is the relay

Continous cutting of fan even after changing alternator and related purlins. So what is the problem?


Check these parts........... First check the TEMPERATURE/RADiATOR FAN SWiTCH, it is connected on ur RADiATOR, w/ 2 wires connected to it, at certain temperature the switch turns ON ur FAN MOTOR, by disconnecting it and JUMP/SHORT the 2 wires FAN MOTOR should run, even when u just turn on the ignition! If the FaN runs, u got temp switch prob and needs to replace, If the fan didn't run when u shorted the wire in the switch. Check the RELAY, located in the ENGiNE FUSE box, pull out the relay and replace it w/ another relay, while ur 2 wires in the temp switch is on and ur ignition is in the ON position, when the relay clicks and the fan runs, u have a GOOD relay, if not u have to replace the RELAY! Hope that explains everything! Taah!

What would cause my fan in my 97 saturn sl not to run to cool off the engine?


well the fuse or relay,or the coolant tempurature sensor is not sending the correct temp, to turn on fans. here is how to see if fans are bad. run a wire from battery positive to positive on fan connection. then run a wire from negative on battery to the ground cnnection, if the fans are ok they will turn on. you do not need car on to test fans. check fuse and relays first.

My camry 1993 engine is heating up while idling or in traffic also when ac is on. drives well on high speed without overheating


You have a radiator fan motor that is not running either due to a thermostatically controlled temp switch,(Located on the back of the radiator) a failed fan relay (in the engine compartment fuse /relay box) or a bad fan motor.
You can troubleshoot by checking for 12V DC to chassis ground at the fan motor temp switch. If you have power in you can jumper with a wire the switch wires and see if the fan runs. If it does not run then you need to check the fan relay and motor.

To test the fan you can run a wire from the battery to the fan and another wire to chassis ground to see if the fan runs. If after directly connecting 12V DC to the fan motor and it does not run the fan has failed.

As far as the you either replace it with another one or... have to figure out which 2 wires control the fan motor and jumper them out to see if the fan runs.

03 grand cherokee, 4.0, rad fan will not run, checked fuses and replaced relay under headlight


Check the coolant temperature switch. You should have 12V on one side of the switch. If you jumper the two wires in the switch connector, your radiator fan should run with the ignition switch on. If it runs, replace the coolant temperature switch.

1990 BUICK CENTURY RAD.COOLING FAN RUNS ANYTIME KEY IS ON.


If you have changed out the relay, and disconnected the temp cooling sensor, make sure you have replaced the correct relay; I believe there is one bank of four relays located by the passenger side head lamp. If the fan is running continuously, then I would say the relay is stuck in the closed position, resulting in completing the electrical circuit, powering the fan. Have the new relay tested. You can find a wiring schematic in the Hanes manual for your make and model.

Radiator fan stays on all the time and car runs rough


The fan relay may be malfunctioning (the fan relay is what actually switches the fan on and off and gets its signal from the ECM, which in turn gets its signal from the temp sensor) testing/replacing the relay and temp sensor would be the best thing to start with,... unless you notice any additional (non factory) wire attached to the power wires to the fan.  Sometimes folks, in an attmpt to fix  an overheating or fan relay problem, attach a ignition switched positive lead from the fusebox or other switched source to the positive poer lead on the fan,.. making the fan run whenever the ignition is switched on.
