Cooling system fan comes on for a few seconds and then turns itself off

I own 2016 CX-3 Sport and am having problems with the cooling system fan.

Cooling System fan comes on for a few seconds while AC is on then it turns itself off. Then after a couple of seconds, it comes back on again to run for a few seconds and then again it turns itself off. And this repeats itself until I shut down the car.

What should I check? I have heard that I should run the car without AC on to see if it happens again when the fan comes on.
I will try that tomorrow but in the meantime any other ideas?

It comes on every time the compressor cuts in. Itís normal.

I am happy to hear this is normal.
I will monitor the engine temp and might revert back with more questions ...

What kind of project you got going on that you needed most of the front-end bits removed? Doing some mods?

Sorry for late reply - I bought my CX-3 used and it looks like it had some work done to the front, so I am checking if all parts are firmly attached and nothing is missing. I was thinking I might have a problem with cooling hence my post here.
