Mine doesn't at all and I believe Im having AC issues due to it.

Shouldn't it kick on after you start up the AC and car gets a little warm?

Thanks

I don't know when the fan IS supposed to come on, but here on NAM I've read lots about the Low Speed Resistor burning out for loss of Low Speed Cooling fan operation.

With the a/c on, the low speed fan goes on at an a/c system pressure above
8 bar and on high speed at above 18 bar, regardless of coolant temp.

As far as coolant temp, low speed above 105C, high speed above 112C.
