The relay that controls the fan may have been stucked close. Pull out that relay, the fan should stop. Then examine the relay. Put 12volt to it, it should click, then click again when power is removed. If relays is okay final check is the temperature sensor associated with the cooling fan. Make sure it is not shorted. The resistance should varry with temperature. Use an ohmmeter, and dip it in hot water. Resistence should get lower as you dip in hot water. vice versa. Do the relay check first before doing all these CTS(coolant temperature sensor) check.

Mercedes Benz GL320 fan turns on after car is turned off. Stays running until your turn the key but you do not have to turn the engine over for it to stay off


On most modern vehicles the engine cooling fans are electric. These fans are thermostatically controlled and will continue to run even after the vehicle is turned off and until the engine cools down. If you feel the fan is running an excessively long time after you turn off the vehicle, I would recommend you have it looked at by the dealer.
Good luck.

When I turn the engine off the engine cooling fan stays on and does not shut off


depending on the engine temperature the fan is supposed to remain on after you turn the engine off, until the engine reaches a preset cooler temperature. when it reaches cooler temperature usually within 5 minutes or so it should cut off... if you cut it off and it is running 30 minutes later.. then there is a problem with the fan relay or temperature sending unit.

Cooling fan won't shut off.


If an engine is hot, the cooling fan will continue to run even after the engine has been turned off.
If the fan runs when the engine is cold, you probably have a temperature sensor issue.

Cooling fan runs continuously, even after replacing both relays coolant sensor.


Could be that you have 2 Thermal sensors as some cars have one for the dash gauge or light and the other is for the PCM.

Remember that when you turn on the A/C it can trigger the cooling fans to run continuously. If the A/C is left on while you are doing all of this, it can be a simple reason for the problem.

I have reno megane 04 my fan continues running when my car is not running i have had the air presureit has just happened again sensor replaced bu


Many cooling systems are designed to let the cooling fan continue to run even after shutting down the engine...however, this should only last for a minute or so...your owners manual may help. If the fan never stops when turned off this is probably a faulty resistor...may need a good mechanic to confirm which...Hope this helps.

1991 honda accord lx cooling fan


Some vehicles have sensors that can control the electric fan with the ignition off to keep the heat buildup that naturally occurs right after turning off the engine. This can prevent hard starting that can happen with a hot engine. If it is doing this an abnormal amount, the sensor that is operable with the ignition off may be failing. Before turning off the ignition, check to see if the engine temperature is pushing the 'red zone;' if it is, then the fan operation may be normal but your engine may be running hot.

My ford excusion vent fan is running even when engine is off. No key in car and I can turn my vents all the way up and it will blow tons of air into car?? Ran battery out overnight.


If this has EATC automatic temp control. You will probably need a blower speed control module. This controls fan speed in all ranges and sounds like it has internally shorted causing this concern.

95 grand am radiator fan only runs with AC on


Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson
