My 2000 Hyundai Sonata Radiator Fan is only working sometimes. Over the past month it has started to overheat twice. It seems to be intermittent, isn’t happening all the time. Someone looked at it and said that it started when he turned it and said that the motor going out. Does that sound right? Will it work intermittently until it just goes out? Wouldn’t it do the same thing if it were a sensor just not telling it to come on? If the sensor was bad, would the motor keep turning once it was pushed started, or would it just not send the message for it to keep running? I’m assuming that he checked the sensor, but don’t know for sure. I’m guessing that there is a $$ difference between the two parts and just want to see if I could check something else before I order the fan.
Answer: I would venture to guess that the fan is going bad. you can verify by turning on your A/C when it is overheating. If the fan kicks on and off with the A/C it most likely has a bad sensor or even more likely a bad wire in the sensor circuit.
