Cooling fan will not turn off

Engine compartment left relay box

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.

bad temp sensor

Most cars with electric cooling fans incorporate a feature that will turn on the fan after the engine has been turned off until the radiator has cooled down. If it keeps coming on after cool down and is draining your battery, then you need to replace the switch that controls the fan.

The only way to protect the battery, is by disconnecting the positive harness from the (+) terminal of the battery. If you want to stop the cooling fan, then unplug the wires from the connector, but the car will owerheat in idling. Might be a bad temperature sensor or something else. If the service engine soon is on, then decode it, find the code explanation and find a way to fix the problem. This car has to be inspected in a mechanical shop, befor the battery is lost.

What happens when you leave the relay out? Your fan control module may have a shott.

its all electronic and fortune to fix ,cut the solonoid feed wire from the loom the thin one that makes the solonoid click on ,not the big heavy wire and fit another relay using this wire thats wired through the ignition switch so when the ignition is turned off it will isolate the original feed wire to the original solonoid

You will need to check the coolant fan switch located on the engine most likely at or near the thermostat housing. It is solely for the computer to monitor engine temps and to either operate the fan it self or to inform the computer that the engine needs to be cooled down thereby turning on the fan by means of commanding a relay. The A/C is able to independantly operate the fans based on refrigerant pressures.

couple posabilities first run car up to temp then turn off...when fan stays running unplug the coolant temp sensor for the fan< there are 2 other is for comp/gauge> if fan turns off replace sensor if not replace relay for cooling fan

Glad to hear that you are all fixed up!

The sunroof leak is caused by a blockage in the drain tubes. Please make sure that your dealer cleans the sunroof drains.
