Aircon clutch started smoking arriving home. Checked the system and was empty.... Was surprised of not finding a pressure switch on the Outback to prevent this:

Aircon compressor seems seized, once cooled down I could move it by hand but was rough. Next thing would be to trace the leak, maybe the condensor?

Any of the seals could be gone but also check for corrosion on teh right had side of the heat ex-changer behind bumper
