    possibly a shorted relay. pull out the fan relay and swap it with the horn relay. If the fan relay makes the horn blow, get a new relay.

The fan is probably ran from an engine coolant temp sensor, which would cause that.but if it stays on for a long period of time{like 30 min} after the engine is off, the sensor could be bad

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.

Volvo s60 fan stays on


Fan should run for a while after turning engine off. However, the most likely cause is the cooling fan module which is attached to the cooling fan assembly.

2002 Suburban_ Engine off but air stays on. When engine is on a/c light stays on & ait stays on even if the fan is turned off


Fan will run for a certain period of time after shutting down motor of vehicle. This is normal. Your engine is still hot when you turn the key off. There are sensors that tell the computer when the engine is cool enough for the fans to shut off.

Fans will not turn on therefore cause vehicle to overheat


cooling fan will not come on until about 230 degrees, if fans still do not work. check the fuses and relay. if ok then run a wire to fan from battery.on fan side connection, run a wire from battery positive to fan connection. run a wire from negative to ground connection.if fan will not come on it is either bad or the coolant temp, sensor is bad. because this sensor send info to pcm from various running conditions. it is very important that this sensor works. it can cause;
  • Extended crank time when the engine is cold
  • Poor fuel economy
  • Spark knock
  • Lack of engine power
  • Erratic and/or high idle
  • Engine cooling fan stays running all the time
  • Engine cooling fan fails to turn on
  • Engine overheating

    My engine fans keep turning on after i turn off the van...and the engine light its on due to that...?


    An electric fan will stay on even if your engine is off. It does that to cool your engine. This itself should not cause your check engine like to come on. Hope this helps you.

    Radiator Fan Stays On


    A simple test would involve disconnecting the fan switch while the fan is on. If the fan then stops the switch has failed. If the fan continues to run remove the relay , if the fan then stops the relay has failed.
    Various inputs/outputs at the relay should be confirmed to be 100% certain something strange isn't going on.
    Above all be careful of the fan itself , if it's running obviously but if it's not it could start during repair

    2 year old Nissan Versa hatchback started making high pitched (low, but annoying) sound and remains on when engine turned off. Located on driver's side of car. What could this be caused from?


    I had this problem and it took an engineer from Nissan Headquarters to fix it. You may have a belt of wires from behind the dash that have been worn and are causing a short. When the car is wet, the sound can be worse.
