Rogue Hybrid AC Failure
Summary of the thread
The air conditioning in a 2020 Nissan Rogue Hybrid stopped working, with an error stored and a warning light on. The initial suspicion was a defective AC control unit. However, it was suggested to check the refrigerant level, as a leak could cause similar symptoms by preventing the compressor from running. Ultimately, a certified workshop confirmed that the refrigerant compressor had failed, leading to its replacement.

I haven't checked the refrigerant level myself due to a lack of tools and knowledge. Is there a straightforward method to verify the refrigerant level without professional equipment, or should I have a technician assess it to avoid potential damage?

DIY refrigerant checks without proper tools can be risky. Avoid that. The pressure can be dangerous if mishandled, and you could introduce contaminants. Based on the symptoms and mileage, a faulty AC compressor or control unit is a real possibility. Take it to a workshop for a proper diagnosis.

I took the vehicle to a certified workshop. They confirmed the refrigerant compressor had failed. The repair, including parts and labor, was 980€. Thank you for your help in diagnosing the issue.

Sounds like a potential issue with the AC compressor or its control system. The error code and symptoms point to that. The AC system not switching on could be the control unit preventing operation due to a detected fault, as a safety measure. Before blaming the control unit, have you checked the refrigerant level? A leak could cause similar symptoms, as the system prevents the compressor from running when refrigerant is too low. If the refrigerant levels are fine, consider the control unit.
