I was thinking the same thing, that the ECU is grounding out the voltage that would normally be directed towards the A/C clutch coil. ECU issue sounds the most reasonable, as it’s not uncommon for a damaged micro-relay to “chatter” rather than seal closed.

This problem has been going on for over a year, so I would “assume” :ham: that if I had a TPS or MAP giving up the ghost it would have totally eaten it by now.
