You most likely have a bad a/c - heater controller in the dash......
no, only 1 fan usually runs unless the air is on and then both fans run.
no Justin wont unless she cry's or if there friends or if she his fan or biggest fan
Replace the climate control/fan circuit fuse.
Because its probably not working. Try turning on the AC to see if they both kick on and make sure to do this when the car is warm. If the car is cold they fans wont kick in.
TO COOL IT DOWN
Yes, if it is a 12 volt DC fan.
Check the fan temperature switch at the bottom of the radiator. A good switch will complete the circuit and turn on the fan on when a certain temperature is reached. Test the fan by running jumpers directly to the battery.
No, not always.
The fan turns on when you turn your car off so that the engine will cool down faster. It should only run for a few minutes, 10 max. But your fan also runs when your car is on not just when it is turned off.
fuse, wiring.... how long do u let it run before turning it off??..I would look to the fan relay next. also the electric fan thermostat if the car has one
Check the fan's fuse in the fuse box. it may be a bad one.
Several possible problems. Temp switch that controls fan has failed, fan itself could have failed, thermostat is stuck open so engine is not getting hot enough to turn on fan. also check the relay on the firewall. I think it is the second or third relay
