Megane Hybrid AC not cooling
Summary of the thread
The AC in a 2021 Renault Megane hybrid has stopped cooling entirely, despite the fuses being fine. Possible causes include a faulty AC relay or defects in individual valves within the AC system. Given the complexity of hybrid systems, a workshop visit is recommended to diagnose and resolve the issue.

No unusual noises. Given it's a hybrid, could the electric motor influence the AC system? Or could the AC relay still be the cause?

It was the AC relay for me, but since your car is a hybrid, it might be different. I suggest a workshop visit. I've heard individual valves in the AC system can have defects.

Thanks for your help. I'll schedule an appointment to check the valves and diagnose the AC system. Estimated repair costs are around 1000€.

I had a similar problem with my 2018 Opel Insignia. AC stopped abruptly. A faulty AC relay was the culprit, easy to replace. But given your Megane is newer and a hybrid, the problem might be more complex. Any unusual noises from the AC compressor area before it stopped?
