A/C runs cold, then stops, then runs cold again?

Thank you for your excellent videos and your offer to answer questions!

Our vehicle listed above is having A/C problems. Last year, when it stopped working entirely, I did research and discovered that I could replace the compressor clutch relay (common problem apparently in Acura's) - that fixed it.

This year, it runs well when the car starts, and usually works for 30-45 minutes, but then stops blowing cold air (it still blows, just more humid, less-cold air until it turns warm sometimes). But then it sometimes/often starts blowing ice cold again, and I'm not sure why.

I've tried replacing the A/C Compressor Clutch relay again, and then tried replacing the Fan Control, Radiator Fan, and A/C Condenser Fan relays.

What I've noticed is that when I start the car, the A/C works right away, but when I watch and listen in the engine compartment, both fans spin hard at first, but then I hear a click and they slow and stop spinning, but then start up again, so it's a constant cycle (usually about 30-45 seconds on, 10-15 seconds off).

I bought a digital gauge (the kind that fits on top of a top-off can) and tested the Low Side pressure. When the fans are on, it reads ~47. When I hear the click, and the fans go off, the reading drops to ~15, and then continues to go up and down along with the on/off cycle of the fans.

I also just noticed that the radiator coolant reservoir is low (nearly empty, though the radiator itself is full), so I'm ordering Acura Type-2 coolant to add, but I didn't think that alone would cause the A/C problem.

Any suggestions or directions you can provide would be greatly appreciated! Thanks in advance!

I can provide video with sound, if that would be helpful.
