Lights went out and radiator fan stays running after car is shut off


It sounds like an alternator, yet you say the fan still worked after you disconnected the battery? And the car was still running? Or the car died out. Sorry, need some more details on this one.

Radiator fan will not shut off


In some vehicles, the radiator cooling fan is controlled independently by a thermostatic switch. What you perceive as a problem actually is normal operation. When the temperature reaches a certain point, the fan turns on. When you stop and turn off the ignition, the fan continues to run until the temperature decreases to a point where the fan turns off

2003 Mitsubishi Galant 2.4L 4-cyl is having trouble holding a charge on the battery. Tests say battery and alternator is OK. I checked fuses and they were good. I can jump the car but after I drive it...


Most likely you have something draining the battery. Quick way to tell, disconnect the ground (negative) cable to the battery, let it sit for a few hours, then reconnect it and try to start it. If it starts OK, you know the battery is holding a charge, but something is draining it.
To drain it in just a few hours requires a serious draw, like headlights or the cooling fan. It is possible that your cooling fan (behind the radiator) is staying on all the time. Often they are controlled by a thermostat, and will run for a few minutes after you shut off the engine, but it should shut off within about five minutes. If it is still running after ten or more minutes, you have a bad fan thermostat or a bad fan relay. If that is not the problem, you will have to get someone with an ammeter to measure the current draw, and start pulling fuses until you find the culprit.

Engine cooling fan runs continuously after engine is shut off to the point that it drains the battery. This just started. I had to disconnect the battery to stop the fan and prevent the battery from going...


My fans did the opposite and wouldn't come on at all. Last year I went through the same process (KMANIAC again being a big help), but it turned out to be the temp sender unit. Maybe a good bet is to replace them both at the same time. I think the TSU was only about $15-20

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.
