Re: 2005 wk ac compressor
Your low side pressures look fine (though I don't know what your ambient temperature was).
With it cooling properly, and not cycling more than 10 times a minute, and your low pressures within normal range I think you are safe to leave it alone.
If you checked the high-side pressures and that was too high, in combination with the low side being normal, it could indicate a low refrigerant condition, but since you are getting cool air I doubt this is the case.
It sounds to me like what you are reporting is completely normal operation. The compressor activates when the low side is above a certain value (I believe 30 PSI). It sounds like on MAX, the compressor is running due to heat load on the system.
