So the car has been overheating and I know that it is partly due to a bad head gasket but also found my fan wasn't turning on. I connected it straight to the battery and it worked fine. soes this mean I have a bad relay? Can I swap it with one of the others just to check?

Thanks

 

check ur fuse

 

I hadn't found any bad fuses but will double check, I will swap it out as a precautionary measure.

Can someone explain what a relay does

thanks again

 

Essentially it's just like flipping a normal switch, only its flipping action is controlled from a remote source.

in other words its active/on when you need it and passive/off when you don't

Unplug the connector at the fan with the car warm and see if you have source voltage. If you do, the fan is bad. If not, check the wiring.

 

The fan switch on your thermostat housing is more than likely the culprit, unplug the connector and jump it with a piece of wire and it will make the fan run while the car is on. Its not a permanent fix but it will help until you figure out what is wrong, or you could just leave it.....it won't hurt anything

 

Thermostat?
