AC intermittently working

The ac randomly just shuts off and then starts again, i can hear the ac compressor turning on whenever i turn it on/off but the ac itself only sometimes works. It usually works for several seconds before stopping completely as in no air coming through. I've searched through a bunch of threads about this, but none of them confirmed it. I am suspecting an FSR issue, as it is one of the most common things to cause randomness in the AC. I just wanna know if anyone else has dealt with it and whether it solved.

I bet the AC system is low on refrigerant.
I'll get it checked in 2 weeks I ordered the fsr just in case because I really need that ac to be working during winter time.
Thanks for the response
If your AC is working but you are not getting air coming out of the vents regardless of fan speed intermittently that is a result of a failing FSR.

Once you get it replaced let us know the outcome.

then just turn the fan to high with AC off, and see if air is blowing out the vents.

Tried that it is not blowing, however I noticed something odd, while driving at around 100 km/h there was heat coming through the vents which I assume is coming from the air going under the hood and the occasional fan kicking in.

Fresh air blew into the cabin and warmed by the heater core -- nothing odd.
So just changed it, it was a huge hassle to get it replaced due to it being an awfully small spot and me being a rather big guy but got it done and it works perfectly fine. So it indeed was the fsr causing the issue.
