Radiator Fan does not work on 1980 Spider2000

[bocajrs]

As the subject line state, the radiator fan will not come on and of course the car overheats if I don't watch the temp gauge. I replaced the radiator last year, and noticed that on the radiator, on the driver side lower half, there is a plug with wires coming out of it. Those wires don't lead anywhere given that they are cut. I assume this is the Radiator Fan Switch?

I did check the Radiator Fan itself to see if it works by connecting directly to the battery with two cables. It works.

So is my problem as simple as buying a new Radiator Fan Switch and plugging directly to the wires that come out of the Radiator Fan? And does the switch pictured below connect directly to the wires coming out of the fan?



Thanks in advanced and please excuse my ignorance as I'm new to the idea of trying to fix my own fiat.

What is your radiator fan connected to now? On my 72 the sender has two white/black wires. One goes directly to the fan motor and one goes to the fan motor relay. The fan motor has a blue wire going to the relay. I don't know how different your model would be. Do you have a wiring diagram?

The wiring for the fan is pretty simple. One wire going to the fan carries 12v the other wire goes to one of the wires on the switch. The second wire on the switch connects to ground. That's all there is too it.
Check Brad Artigue's excellent website for wiring diagrams.
Here's the one you need, the fan is on pg6.
