Hi again :)
2000 blazer. My A/C compressor clutch is cycling pretty often. I'm trying to find out about how often its supposed to cycle. I'm in Houston, which is often hot and humid, but even at night time when its cooler and drier, its cycling between 5-15 seconds.
That sound normal or should I look at the pressure switches? I've had it checked for leaks and refridgerant level, both are good. Don't think I had the UV test, just the freon sniffer machine that you run around the system, looking for anything.
Plus its been doing this for several years. A/C runs cold. Probably would have leaked out by now if it did have a leak.
Does this sound normal to you? Had a few people suggest looking at replacing, cleaning or replacing o-rings on the pressure switches.

We need the low and high side pressure readings at idle and at 2000 rpm.
