Several sensors, Air temp, evap temp, high and low pressure can create problems.
It's possible that the clutch is worn causing what you described but a worn clutch usually does not cycle with your on 3 on, 15 off times. As others have suggested you could have a mechanical problem with the flow of refrigerant, like an expansion valve - but those once they are clogged usually don't work properly until replaced. However your previous compressor failure could have put shredded metal in the system, partially blocking the condenser or expansion valve.
A set of gauges and Vida hooked up to the car (and having the failure occur) should be able to help with diagnosis.
Completely agree.
With a recently replaced compressor, actual troubleshooting is required.
I had a similar problem on the XC, and it turned out to be an evaporator temperature sensor. A $25 part that took 20 minutes to install. Easy fix.
But KNOWING WHAT PART needing replacing was critical. You’re at the “speculation” phase of repair. A very expensive and frustrating place to be. Two paths before you:
1. guess and throw parts
2. troubleshoot and diagnose.
Please find someone that can do the latter. The former is common, and very hard on your sanity.
And your wallet.
