So I quickly researched variable displacement compressors, and apparently they don't use a magnetic clutch.
My ac compressor clearly has magnetic clutch and mag clutch relay.
Does this sound like a variable displacement pump still?

Wow, thanks a lot for all the replies. I had no idea it was normal for the needles on a manifold gauge set to stay still with the ac compressor running on a variable displacement pump. And I had no idea it was normal for magnetic clutch to stay engaged all the time. I was thinking there could be som...

I have to research more if this is a variable displacement pump.
But shouldn't my gauges move either way?
I didn't see any evidence anything is happening on my gauge set. And I know my gauge set is ok.

Customer complaint. They say it stops blowing cold. I didn't get to inspect it for long, but I've never seen a AC system run like this. I am used to older vehicles... Normally that magnetic clutch cycles on and off. And with gauges hooked up I can see when the clutch engages and the compressor start...

Hello everyone, I have a problem I haven't made sense of yet. I've never encountered this before. Just wondering if anyone has any advice. My AC Compressor clutch in engaged. Clutch is turning. There is pressure in the system. 50psi Low 150psi High. But the system is not compressing. The gauges don'...
