Clutch Relay Circuit
This question indicates that there's a short to ground at point D of this circuit. This circuit is ground controlled by the PCM. If there's a short to ground before the PCM, the clutch relay would remain closed whenever the circuit is powered. This would cause the A/C clutch to stay engaged.
If the circuit were open at point D of this diagram, the A/C clutch wouldn’t engage. This would indicate an open or break in the wire leading from the relay to the PCM. If there were an intermittent condition, where the clutch works one minute and not the next, suspect a loose plug or connection at the clutch, PCM, fuse, or the relay itself.
