Maybe a stuck relay. Find the relay for the fan in ther car manual and replace this first because it's cheaper. You can also check the temperature gauge for the motor too because this may be telling the fan to stay on.

SOURCE: 3.8litre ,electric fan continues to run killing

The electric fan relay has gone bad and will need to be replaced. The relay is sticking to the on position causing your fan to constantly run. The relay is located in your fuse box in the engine compartment i believe.

Good luck and thank you for using fixya

Cooling fan stays on after turning off car


Taken from other previous solution (but it's right): the cooling fans are switched off and on by a relay. either this relay bad and staying on all the time, or something else is bad and telling it to stay on all the time. you might unplug the engine coolant temp sensor and see if the fans switch off. if they do you have a bad temp sensor, if they don't you probably have a bad relay. they will test either for you at most car parts stores. the relay will be in the underhood power distribution box, it plugs in like a fuse. disconnect the battery negative terminal before you start unplugging things from the power distribution box. hope that helps

Ac fan runs even when off pulling down the battery


I am not familiar with the X5, but most cars electric fans are controlled by a thermostat. If the thermostat, or the associated relay is stuck or defective, this could cause this problem. BE AWARE however that most fans stay on for a time to cool the engine, even after shut down. If your battery is weak, the fan staying on could draw the battery down.

3.8litre ,electric fan continues to run killing battery.doesn't happen all the time.


It is most likely the fan relay is sticking and allowing the fan to run on, the relay is plugged into the fuse/relay box on the drivers side of the engine compartment.

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 2003 chevy cavalier electric fans wont turn off


Usually after driving, your rad fan can continue to run for up to 2 minutes after shutting off the car. It can even start up on it's own if it detects that the temperature of the engine is too hot (say if it's over 50 degrees celcius). The fan running for these several minutes should be of no concern. If it's staying on and not turning off for 30 minutes, then that is of concern

I have a 2004 chyrsler sebring v6 and recently my fan started not shutting off when i turned the car off and now its killing my battery does anyone have any idea what would make the fan stay running even...


Check under the hood and see if you have a decal that says fan may turn on after car is turned off. The fan can run for 10-15min after shut-off.
If it's on for only that length of time and it's killing your battery, you may need a new battery.
If it's not turning off at all, open fuse compartment under the hood, take a small rubber mallet and start to tap the relays. There should be one there for the cooling fan. Once you find it, (the fan will turn off when it's tapped) you can exchange the relay for another (of the same part number - like the wiper relay or A/C relay or something) restart car, let it run til hot, and turn off. If fan shuts off within 10-15 minutes, you need a new relay.

My cooling fan will not turn off and it kills my battery


when you say the fan won't turn off is it on all the time or does it stop after say 1/2 hour ?? if it turns off i wouldn't worry about it as when you stop the motor will naturally get hotter but if it stay on full time it could be the heat sensor component that controls the fan hope this helps regards Jim
