I noticed that AC is not blowing too cold. I started reading forums and discovered that when AC is on the low-speed fan should turn on. For me it does not.
I checked fuses - all good. I tested high-speed fan - Its come on after 104C.
I checked relay and it seems ok (it passes current when I apply load - but i do not hear any audible clicks)
This kind leads me to believe that resistor has failed resulting in low-speed fan not turning on.
With the AC on, does it short cycle into super HI mode for about 5 seconds and then shut off? If so, the resistor is bad and you need to replace the entire fan assembly. Rock auto had what I needed for about $95 shipped to my door in a day. I did most of my work from under the car, there are only a couple torx screws and the process was like the pelican article. The electrical connection twists off with a small bracket fastener if I recall correctly.

Tested more. With AC on fan does not come on. It only comes on after I reach 102 deg C. (high speed?)
I tested fan relay and it works (it clicks and i also swapped it with engine relay and engine still starts). All fuses are good.
I used a jumper cable for fan relay and low speed fan comes on - so fan itself is not a problem either. Air blows cold when it is shorted.
It leads me to believe that the control circuit for Fan relay is not getting energized.
Not sure where to go from here. Faulty ECU?
I may bite the bullet and take it to the dealer for diagnostics I guess... :-(
Well, the problem with forums is, sometimes you have to be careful about what you are reading.
According to the technical decription listed in newtis.info, fans in the non-turbo cars have one speed. S cars have two. Below are two clips from the website, the first being for the N12 engine. Notice the single stage fan has a 2-pin connection, and the 2-stage fan has a 4-pin connection.
F56 came in 2014. Mine is last model year for R56.
And yes, you are right. mine is single speed (2 pin connector). It is supposed to come on as soon as you turn on AC (I tested this on another MINI)
The fan itself WORKS. I tested by applying a jumper to the relay - and when i did that AC did blow cold as expected
The fan also turns on at 102C so relay is not an issue either (i also tested the relay and even swapped it with another relay)
So i think I am not getting signal from ECU.

Looks like F56 production dates start as early as April of 2013. That's why I was asking because your car is so close to the model change, and the cooling fans work differently.
Here's my suggestion. Connect a Foxwell NT520 scanner to your car and pull up the IHKA or IHKS (automatic climate control or manual). Select "live data", and then select the AC switch, then press F3 to view the data. When you depress the AC switch in the car, the scanner will allow you to see the position as the IHKA/IHKS module see it. This will tell you if the switch is sending the signal to the computer module. If you don't have a scanner, contact elly@foxwelltech.com for a price quote, or you can get one from Amazon if you want it fast.
