I woke up this morning and my car would not start. I jumped the battery and let my car run for a few minutes, then I turned it off. But when I tried starting it a couple of hours later it was dead again. I noticed when my car was on, that my engine fan would not go off, even when my car was off. Could this be the reason that my battery is dying? And if so what can I do to fix it?

Sounds like the alternator isn't giving the battery a full charge. I would go to a checker auto parts and have them test the alternator. My 05 altima's battery never drained and the fan ran almost continuously to keep the engine cool. Does your dash have a volt meter? Try to jump the battery again and see if when you are driving if the volt meter rises or falls. That'll tell you if the alternator is bad. But this is only over the computer advice. I haven't drove your vehicle nor have had access to it. So, seeing as my husband is a mechanic and we've done the bad alternator thing a time or two that's the best advice I can give you.

Yes, it probably is the reason. The fan is switched on and off via a sensor that detects the temperature of the coolant. Just follow the wires from the fan and you'll see where they connect to a thing that sticks out near the radiator or engine block. That's the sensor. It sounds like the sensor has failed. They're not expensive and it will only take a few minutes to change at any good garage or service center.

When you jump the car, do you leave the two cars connected by jumper cables for about 10 minutes? Try that, then after disconnecting the jumper cables, go for a drive near home for 20 minutes or so, so the battery gets recharged.
After you get back home, and give your car a rest, try starting it again. If it doesn't work, the alternator may need to be replaced.

Modern cars have electric fans behind the radiator, as you've discovered. They are controlled by a thermostat in the cooling system. If the 'stat is faulty, the fan will run continuously, and, yes, it will drain the battery. Note that the fan should run a short time after the car is parked if its hot. It should not run first thing in the morning right after startup. If it does, suspect the fan thermostat.

When you turn your car off if anything is still on or running it's drawing juice from the battery and will run it down.
