Fan switch died for the 3rd time.

I'm not talking about the blower motor haha
What i mean by fan switch is the sensor that screws into the thermostat housing that turns the radiator fan on and off.

And I'm not talking about the "fan switch" but responding to side issue raised by WRC regarding oiling motor. haha

Wiring a fan swtich with a fuse and relay isn't at all difficult. Assuming it's a one speed fan, you just take the current supply to the fan to trigger the relay, take a fresh supply then from the battery, through a fuse through the relay to the fan. Something I'd happilly draw up for you if you needed the help.

So we aren't talking about a switch then?

These are what we call switches over here, and what I think most people are referencing.

I knew what he's talking about:

(commonly used in vehicles with electric cooling fans before they started using the ECM for fan control around the late 80s/early 90s)

Electric radiator fans always use a lot of current. After the first generation with them in the 1980s, car makers universally went to having a relay because the switches didn't hold up to direct switching.

I had a 1985 Ford EXP which was basically a 2-seater Ford Escort. The cooling fan thermostatic control quit on it when it was about ready for the scrap heap and the fan wouldn't run at all, so I hard wired it with a toggle switch under the dash. I'd just leave the fan running any time the engine was running. If I remember right, the cooling E-fan had twin metal blades, yet moved some serious air for it's size.
