AC compressor cycling

[Stl-986]

Dont disagree. Have 2 986 in the driveway right now and both stay on all the time and ac blow ice code and pressures are where they are supossed to be.

My compressor doesn’t seem to cycle on and off but the clutch engages and disengages regularly keeping the temp steady. I would think if the fluid was always flowing you would get a frozen expansion valve. Maybe an HVAC expert will chime in here.

When I say the compressor cycling on and off, it really means the clutch engaging and disengaging.... that I never hear with my car once AC is turned on. It blows cold air and temp can be modulate, but apparently the compressor is always running.
