Lexus RX Climate Control Failure

Alright, Lexus gurus, I'm tearing my hair out! My 2012 Lexus RX hybrid's climate control is completely bonkers. The display is dead, the heat barely works, and the AC refuses to kick on. The car throws an error code, and my scanner suggests a wiring issue. Anyone else experience this fresh hell?

Hey, I had something similar happen in my RX. Check the power supply to the climate control unit itself. It might be a loose connector or a broken wire in the harness.

Interesting! Where exactly is the climate control unit located? And were your symptoms exactly the same? The error code is the main thing bugging me.

Yes, that sounds very familiar. I'd recommend getting a workshop to check the cable and plug connections. I am pretty sure that this will solve your problem.

Thanks a lot for the tip! I took it to my local mechanic, and you were spot on – a loose connection in the wiring harness. They fixed it for 95€. Now the climate control works perfectly!
