The ECM will turn the fans on when the air conditioning is on. It will also turn the fans on when the engine reaches a certain temperature.If the air is off, then it is likely a stuck temperature sensor on the fan. It could also be that someone thought the fan was not coming on and wired it direct.

2003 Toyota Celica Rad fan works continuous. Heater is barely blowing warm air I feel like the two problems are connected. The Rad fan comes on as soon as you turn the switch...


Hi S, The fan is not controlled through or by the ECU. I suggest you check the connection to the fan temperature sensor. If it is disconnected the fan will operate. Refit the connector and make sure the connection is making good contact. If the fan continues to run make sure that the relay is not fused and that it is operating correctly. Regards John

The fan motors keeps running after car is shut off. Also sometimes fans start when car is started cold.


If the fans didn't run any further the engine continues to warm and possible seizure will occur. This is also the reason you will probably go through batteries in the long run. Hopefully this helps the issue you are having.

2003 Saturn Vue electric fan always running


Check the fan relay, probably in fuse box in the engine compartment. Check owners manual to be sure. I have seen these melt causing fan to run all the time.
