[Clarky]

My aircon has stopped working and I have traced it to the A/C clutch not engaging.

Fuses and relays appear good and using AutoEnginuity I did a temp draw down test where it overrides the controls and runs it flat out for a few minutes and the clutch failed to engage.
There was a P0645 Clutch Relay Control Circuit code but I may have triggered this when I pulled out the relay with the engine running. I will do another scan tomorrow to see if it returns.

I intend to power up the A/C clutch coil manually when I have a day off work just to confirm if its good or not.

So my question is can I change just the clutch and coil or will I be better off changing the whole compressor.
