Ford Edge AC undervoltage issue

Hey, I'm having trouble with the AC in my 2021 Ford Edge diesel. It's not activating at all, blowing no cold air, and throwing an error code about possible undervoltage to the AC compressor. Anyone else run into this?

Ugh, tell me about it! I had a similar freakin' issue with my Edge, though I can't remember the exact year. Was sweating like crazy. Is your HVAC system completely dead, or just blowing warm air?

The HVAC system seems totally unresponsive; the AC compressor isn't even trying to kick on. What was the specific issue you had?

Yep, sounds like the exact same headache I had. Seems like the pressure switch or something similar gave out due to some electrical gremlin. Honestly, I'd just take it to a workshop. Saved me a ton of frustration.

Took your advice and brought it in. It was undervoltage, which was shutting off the AC compressor. Cost 240€ to fix. Thanks for the help!
