(EDIT: Added more clues, Scooby Doo.)

A/C went out the other day, so i checked fuses and relays today (no problems there), then checked out the condenser compressor clutch... holy shit, its broken!

I have no idea how this happened. I dont even know how to begin repairs.

  • Up until last weekend, it was working... not great, but at least working.
  • System has plenty of charge (tried that first).
  • I can get about quarter-turn either direction on the compressor shaft before it starts offering resistance, and then I can’t turn it by hand any further (haven’t tried a wrench yet). I’m not sure if that’s a sign that it still has compression, or that it’s seized.

UPDATE: As it turns out, this particular model of AC compressor does not have an electronic clutch, but a mechanical one built into the compressor body. To that end, the compressor has a “feature” wherein the hub shears off pulley in the event that the compressor is seized. That breakage on my compressor hub is by design, apparently.
