What if the radiator fan does not turn on a 2000 pontiac sunfire?

If the radiator fan on a 2000 Pontiac Sunfire does not turn on, it could be due to several issues, such as a blown fuse, a faulty fan motor, or a malfunctioning temperature sensor. First, check the fuse related to the cooling fan and replace it if necessary. If the fuse is intact, test the fan motor directly by connecting it to a power source. If the fan operates, the problem may lie in the wiring or the temperature sensor.
