Should I look into topping off the refrigerant charge, or is it normal for 1990's GM truck compressors to short cycle like this one?
It seems to work well and blows reasonably cold despite this short cycling, so I haven't worried about it too much, but I thought I'd ask, since it would be awful for the A/C to go out during a heatwave such as the one that's been ongoing out here in California, and being as this is the only GMC of any sort that I've ever had any experience with, I'm not super familiar with what "normal" A/C compressor behavior is, since it has been working like this since I bought the truck back in 2017.
