    When my MCU died, my AC also stayed on. For me taking out the MCU fuse for 30 seconds turned off the AC.

    Thanks for the suggestion. Unfortunately I can’t find the MCU fuse. Here’s my fuse box layout Tesla Model S (2015)- fuse box diagram - Auto Genius

    Tesla Service contacted me soon after my previous post, and found an opening for the car at the service center Monday morning. They asked me to shut the climate control remotely, but no dice. Hope the fan survives this

    Yup it’s that one. Just take it out for 30 seconds and you should hear the the AC compressor turning off while the fuse is out.
