A/C Help Please!!!!!!!!

[Serebros]

help a/c keeps switching on and off, ive been dealing with this since i bought the car

its not low pressure switch (since otherwise the compressor wouldent kick on)

i dont believe its the clutch relay (replaced a few months ago, i can hear it clicking on)

system is full (filled it professionally last week, and came back 3 days later to check for leaks with UV Light, no leaks and system is still full)

took two videos of what im talking about, watch the compressor, this is on a hot day, maybe 90 degrees outside, on a night, it blows freezing cold, 28 degress

what else could it be??? its full, it gets cold, please help me
