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 remains closed whenever the circuit is powered. This short to ground would cause the A/C clutch to stay engaged whenever the circuit is powered.

If the circuit were open at point D of this diagram, the A/C clutch wouldn't engage. This open is probably a break in the wire or the connector/pin 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.
