Hello everyone!
I am having an issue with the radiator fan not coming on at all.
There are already several things that I have tried. At the same time, I keep losing coolant, and have to refill it with water. almost everyday.

I have tried so far..
1. Replaced a fan relay (didn't turn the fan on)
2. jump the fan switch(didn't turn the fan on)
3. check the fan motor(connected directly to car battery and it runs!).

So, I know my fan motor is not dead. But whether i turn the ac on or short the fan switch, the fan still doesn't come on.
Now I am taking my thermostat housing apart today. But it just doesn't make sense that my thermostat is bad, because shorting the fan switch didn't turn the radiator fan on.

Could it be a defect fan relay?

I am at a loss, and is it a possibility that my head gasket is blown. But would that stop the fan from turning on even when shorting the switch?

Any help would be great.

Thanks.

 

What method did you use to jump the switch? Check fuse.
