What exactly happened? Were you driving for a long time? Were you working on the car?

Also a bunch of peoples have done the Fan Delete mod...try that...I think it adds HP or something as well.

yeah, I had just pulled in from a 5 hour road trip. Heard the fan running after I got out of the car, went back to the car a couple of hours later and it was still running so I pulled the fuse. Put it back in this morning and it kicked back on again.

Unplug the battery.
Or try and stop it with your fingers (no joke) and see if it starts back up again.

Gator is an unknown quantity at this point
There is a temperature sensor screwed into the bottom of the radiator which most likely needs to be replaced. Remove the leads and with the car cold, check the continuity between the two electrical connectors on the sensor. There should be no continuity. If there is the sensor is bad.

I was thinking that was it, I think on mine, though, the DOUBLE TEMPERATURE SWITCH is on passenger side of the radiator.

It is on the side. I took it off and cleaned it and the connections not really anticipating anything would happen. Well now it works like it should. Comes on with the A/C and turns off when shut off car.

I have the same problem on my 323 E46, I will try the same.
Do you have a more detailed description of what you did?

Thanks

Mind you this may not have fixed my problem but so far it has, will know for sure after my 5 hour road trip back home today.
On the passenger side of the radiator toward the top is a double temperature sensor with a wire running out of it. I figured I needed to replace that but before doing so I unplugged it and cleaned it and the connections and now it works. I figure its on its way out and this is just a temp fix but we'll see, at least I'll be home. Hope that helps
