Lexus LS AC issue

Experiencing A/C issues on my 2011 Lexus LS hybrid. The A/C won't switch on, so there's no cooling. Diagnostics show an error. The car has 33124 km. I suspect undervoltage. Anyone else had this?

Hey! Similar thing happened with my LS. A/C just quit. I'm no expert, but have you checked the A/C relay? Also, check the belt tensioner, maybe it's loose and not spinning the compressor right.

Thanks. Could you say more about the A/C relay's location and what you saw before it happened? Any error codes?

I'm not 100% where the A/C relay is, check your manual! But yeah, no cold air was the main thing, and sometimes a weird humming sound before it died. I just took it to a workshop. They sorted the A/C relay and pressure switch.

Appreciate the advice. Took it to a local shop. Undervoltage was the problem, and the A/C compressor was turning off to protect itself. Repair cost was 240€.
