Why does fan motor keep running after engine is shut off


This is normal and there should even be a warning label near the fan shroud. It is cooling the radiator and as long as it eventually does go off there is nothing to worry about.

Our Regal's a/c fan was stuck turned on, even w/ the ignition turned off. Draining the battery to dead. My wife took it to a Buick dealer who's only solution at that time was to pull the fuse out. So...


the radiator fans use a fuse,relay,temperature sensor which the computer controls to turn on the fans at the specified temperature.you don`t say if this problem occurred when the blower motor fan fuse was removed.it is not uncommon for the rad cooling fans to seize and not work,the blower motor uses an electronic resistor block on the air box under the hood with i think about 6 wires in the plug and is about 3.5"long and 1"wide.held by 2 bolts(screws).this is feed power all the time and when the control switch is turned for different fan speeds the switch grounds the circuit.at times the resistor shorts causing the fan to run continually.i think you need a new resistor to fix this problem.

The Auxilliary FANS keep on turning ON even if the engine is stop or no ignition please HELP


The fans will run even if the vehicle is off. This is to keep the engine from overheating
after it is shut off. (residual heat). Now if the fans run continuously after the
vehicle is shut off and do not shut off in say, 15 minutes then the fan relay may
be stuck or the temperature sensor has failed. The fans may also come on after
a long drive several minutes after the vehicle has stopped as heat builds up
because there is no air flowing across the radiator. They may even be controlled
by the engine computer in some vehicles. You can have a code check
run at many parts stores for free.
Also, check the coolant
level with the vehicle off and totally cold at the radiator itself to be sure that
it's not low (Even if the reserve tank is full you can still be low creating hot pockets in
the block). Make sure the overflow tubes are connected to the reserve tank
I have seen them fall off and drain the radiator slowly without being noticed.
Hope this helps.

1999 Buick Regal has two distinct problems. 1.


Sounds like you have a blown headgasket,check the coolant in the radiator and if you find oil in it you do need a headgasket.

Both radiator cooling fans won't turn on vehicle overheats


The fans come on only when hot or the AC is on. There are many fuses that have to be good for it to work. The fan relay should have 2 pins hot with the key on, The other 2 should be ground. with the key off one should be hot and the other can then be ground the other pins that are ground one of them is the fan. the other becomes ground when the computer turns the fans on. If you don't have a pin thats hot at the relay all the time then theres a blown fuse or even the power wire from the battery at the battery

The electric radiator cooling fan will not turn off


As long as the fan eventually shuts off this isn't a problem,the fan will continue to run for a bit after the car is turned off,once it reaches a set temprature it will turn off.

1999 grand cherokee jeep -coolant fan will not shut off


Hi Jeepers,

The fan will occassionally continue to run for five or ten minutes after the vehicle shuts down. This is normal.

What is not normal is if it keeps running until the battery drains.

Does it just keep running?
If it eventually shuts off, how long does it take?
Did this just start happening?
The two days you mentioned, were they short trips, opposed to the third day?

If you would comment me back with some more details, it would help me help you.

Electric fans runs after car is shut off, drains battery


Having the fan run on for a bit after the engine has stopped is not abnormal in itself, but 20 minutes sounds excessive.

If the fan does eventually shut off, I'd consider changing the thermoswitch (this is a sensor screwed into the radiator somewhere near the bottom, with a pair of wires connected to it - to change it, you'll need to drain the cooling system).

If the fan stays on continuously until the battery is completely flat, see what happens when you unplug the wires from the thermoswitch. If this stops the fan, you need to replace the thermoswitch. If it doesn't, then you need to examine the wiring associated with the switch and the fan, looking for damaged insulation.
