Both motor fans keep running after car is shut off

When the key is turned off the both motor fans keep running even though the car is not hot and i haven't ran the a/c at all. As soon as I turn the car key on it stops and cycles on and off properly but the only way I can get it to shut off when engine is turned off is to pull the fans fuses

Faulty fan relay, little square box, costs an arm and a leg. Try the local automotive parts recycler, you can't get BWM parts at the junkyard :)
The little box is located, with teutonic efficiency, next to a bunch of little boxes just like it. Check your owner's manual or a shop manual for which one it is.

Radiator fan runs after ignition is off and key is removed


Does the fan motor shut off after a time or does it run your battery down?

If it runs for a time and shuts off, this is normal with a lot of cars today. It is a second stage cooling system that keeps cooling even after the motor is turned off. They all have either a temperature control or timer switch that turn them off.

If the motor runs till your battery is discharged then the temperature or timer control switch has gone bad and needs to be replaced.

Should you find that your car is overheating while in town, then the fan motor or sensor switch are usually what is at fault and will need to be evaluated and replaced accordingly.

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.

Hi just wonder why my 2000 cavilier would still blow hot air when the heater is shut off


The vehicle is probably engineered that way, years back GM introduced what they called Astro ventillation tyo the Chevette line of vehicles, I had just started working for a dealership that was going to be slandered all over the news because they couldn't repair the vehicle from blowing warm air even though the fan and heater slide were turned off.
This was my first job in the dealer after the problem went around the shop for a month or two, I found an article paragraph on the first page of our in house reair manual for heater and air condition trouble shooting Chevrolet Chevette, it stated that the car with the key on whether running or not would keep a constant flow of air throughout its outer body skins called an Astro Ventillation system and its purpose was to keep any toxic and/or flammable gas fumes out of the vehicles cabin space.
It was around for a long time and probablyl is the reason why you have this same condition of warm air flow, its a constant turning of the heater blower fan.
Happy Motoring!!!

2001 Jeep Grand Cherokee Radiator Fan Doesn't run


Have you confirmed the fan has a good ground, sounds like you have eliminated the issue of 12 volts, when you turn on the fan then the AC does the compressor run? if the compressor runs pull the plug to the fan motor and check to see if has 12 volts with a test light, wait for moment because the fan may not run until the AC system pressure reaches a certain pressure point, this means that even though the compressor is running the fan may not always run, There is a quick test for the fan circuit, disconnect the fan sensor at the thermostat housing, the fan should come on, this is failure mode, so if the switch goes open the fan will run to keep the engine from overheating , let me know after the tests are run.
