Q: Cooling fans not turning on, resistor looks rusty, connection not burnt, could it be relay or resistor

asked by on

Fans not turning on

My car has 188000 miles.
My car has an automatic transmission.

I would definitely recommend replacing the resistor if it looks rusty as this can cause corrosion leading to faulty connections which will in turn interrupt the operation of the cooling fans. I would also suggest checking the power continuity to the relay as well. You may also want to consider having an expert from YourMechanic come to your home to perform a cooling system service as a precaution as well.
