Electrical gremlins got me today.

[CKUCF]

Went wheeling today with some water crossings and mud. It’s been raining daily in central Florida so it’s was pretty wet, but the water never reached the doors. Everything was seemingly going well, when suddenly my AC started blowing warm. Then the Auto Start/Stop warning light came on, then “Service Electronic Stability Control” and ultimately my check engine light.
Everything is still running fine, aside from the AC and the start/stop. Anyone have any ideas?

All of them deal with solenoids and wiring.

Odds are your PCM got water splashed in/on and you're shorting across contacts.
Or, each individual system got wet and you have shorts due to water.

Take apart connections, dry, apply dielectric grease, reconnect is my best guess.
