When the engine is on, batteries are being recharged. If you use a lot of electric power when the engine is off, you can drain your battery to the point where it will no longer be able to start your engine, and you will need to jump-start it.

What does the fan do in a car engine?
cools the engine. without a fan, the car will overheat and the coolant will boil. the fan controls this from happening by cooling the coolant as it passes through the radiator.
If the engine coolant sensor andconnector were replaced on a 1999 Saturn sl1 why is the fan motor not working?
bad fan or bad fan relay
Why does the Cooling fan stay on for so long after you turn the car off?
The cooling fan is electric and the sensor reads that your car is hot. It stays on, even when the car is off so that it can cool your engine to acceptable temperatures. If it didn't, and the car remains too hot, it can warp parts and destroy your engine. If the fan runs for an exceptionally long time, and drains your battery giving you a no start or weak battery slow start condition, you may have a bad cooling fan relay.

What could be wrong if the fan is not working to cool engine on 2000 grand am?
check power to fan, wiring, bad relay, bad fan. you can hot wire fan - take 2 wires w/ alligator clips on each end, connect each one to car battery terminal, then ground the NEG wire alligator clip to metal on car, then the POS alligator clip to terminal on fan, if fan is good it will run. Or take 12 volt test light (easier) buy one real cheap, one connector to each of the fan wires & if it lights up - then fan is bad. Cause fan motor has power directly to it so if not run = bad.

What are some reasons why the engine is over heating in a very fast speed?
some reasons under powered engine for car and speed you are doing insuffient coolant in engine bad water pump bad fan hot weather and speed clogged radiator either outside or inside
When I replaced my battery the fan started running even before I started the car.?
It is definitely caused by a problemtic cooling fan relay. When the bad relay shorts internally, it causes the fan to stay on at all times which drains the battery.
