Scenic AC Compressor Fails

My 2014 Renault Scenic with a gasoline engine has 205260 kilometers. The A/C system fails to initiate; the A/C compressor doesn't engage, so there's no cooling. A diagnostic scan stored an error code, but I don't have it right now. I suspect undervoltage. Could a faulty belt tensioner, AC relay, or a refrigerant leak cause this?

Hey, I had a similar thing happen with my Scenic. AC just quit. I'm no expert, but did you check the AC relay? It could be a simple fix, or at least rule it out.

Thanks! Could you elaborate on the specific symptoms you experienced, and whether the relay switch was the problem? Any details regarding your troubleshooting would be great.

Yeah, mine just stopped blowing cold air completely, same as you. I didn't mess with it too much myself, honestly. Took it straight to a workshop and they sorted it. Might be worth doing the same if you're not sure.

I appreciate your assistance. After consulting with a technician, it was determined that undervoltage was the cause, leading to the A/C compressor's shutdown. The repair, addressing the undervoltage, cost 240€.
