Default radiator fan turns on and off

My a/c compressor was cycling on and off so i checked to see if my radiator fan is working. Car was cold and i turned the a/c on high. The radiator fan is going on and off. I cant tell if this is because the compressor is cycling or is the compressor cycling cause the fan is failing? Any suggestions on how to tell?

I have enough r-134a also.

Don't take it to the bank but I would say the fan is reacting to the pump. The why I have no clue.

How did you determine that you have plenty of r-34?

My mechanic just filled it and tested it on the 10th. gonna bring it back to double check the pressure at my mechanics tomorrow though. He didnt detect any leaks at all. I know if i didnt have any leaks then it wouldnt need to have been filled. I have one of those gauges that come on the big cans of 134a and it says pressure is good. It doesnt have stop leak in it either, i know that can cause issues.
