Wait, so the condenser fan NEVER works…?

No, I've never proven it works. The condenser fan "looked" like it was working, it was spinning, but I now believe it's just from the suction of the radiator fan. I pulled the fan and put 12v and it didn't spin, so I replaced it and the condenser fan fuse. The new fan appears to spin too, but it's just the suction again. I don't see 12v at the fan connector, I confirmed continuity on the ground and continuity of the hot side to the relay. I haven't figured out pin 85 on the relay.

Does your new fan run with 12V applied at the connector terminals? You will definitely notice if it is working, there is no ambiguity.

Just for fun, check the A2 ground (ground for the fan) which should be a bundle of white/black wires bolted to the fender on the driver side behind the headlight housing. Maybe something is going on there and it's an easy thing to check off the list.

Yes the condenser fan is strong with 12v at connector and when I jumped pin 87 on the relay. Ground has good continuity.

AC Side: AI diagnosis: At 270k miles, what you are experiencing is almost certainly a heat-soaked A/C compressor clutch (excessive air gap) or a failing magnetic coil
