Lexus NX AC failure

My 2021 Lexus NX hybrid with 116453 kilometers has an AC that's stopped working. It's completely inactive, even after checking basic settings. Could this be a refrigerant leak or a pressure switch issue? Any AC maintenance or diagnostic guidance is appreciated.

I also own a Lexus NX and had a similar problem recently. The AC wouldn't activate. Did you notice any unusual noises or changes in the engine's performance before the AC failed? That might help pinpoint the problem.

No unusual sounds or engine changes before the AC failed. It happened abruptly. Is there a specific component to examine, maybe in the temperature control system? Could a defective pressure switch prevent the system from starting?

Sounds like what happened to mine. I took it to a workshop, and it was faulty valves within the AC system, apparently somewhat common. I wouldn't start tearing into things without proper tools. Take it to a trusted mechanic for proper AC diagnostics. It's faster and cheaper than guessing.

Thanks for confirming a similar experience. A professional diagnosis is best. I'll schedule an inspection. The mechanic found faulty valves. Repair cost will be 1000€.
