Impala automatic temperature control issue

Hey there! I had a similar climate issue with my old Opel Astra, although that was a completely different make and model. My symptoms were slightly different, but the root cause was also related to the climate control system. Have you checked the sensor itself for any physical damage or corrosion? Maybe unplugging it and plugging it back in might help, worth a try!

Thanks for the suggestion! Where exactly is the temperature sensor located? And when you say "sensor", do you mean the actual sensor unit, or something else?

Okay, so on my Astra, the interior temperature sensor was near the steering column, but I'm not certain where it is in the Impala. I meant the sensor unit itself, like the physical component. But honestly, if you're unsure or not comfortable poking around, it might be best to get it checked by a workshop. I ended up going that route myself. Cost me about 100€.

Thank you so much for the helpful advice! I took it to a workshop as you suggested. It turns out the cable connection to the temperature sensor was indeed defective, just like the error message indicated. They repaired it for 95€, and now the automatic climate control is working perfectly again!
