Fusion AC Faulty Temp Sensor

I encountered a similar problem with my Fusion. The automatic climate control became unresponsive, and the air conditioning wouldn't engage. Have you checked the sensor readings with an OBD-II scanner to confirm the sensor's output?

Yeah, I did check the sensor readings. They're all over the place, completely erratic. So, you had the same issue? What was the culprit in your case? Did you manage to fix it yourself, or did you end up taking it to a shop?

Given the unstable sensor readings you observed, the problem does indeed appear to be located within the sensor itself or its associated wiring. In my case, the issue was definitively diagnosed by a qualified technician. While I generally prefer to undertake repairs independently, the complexity of the climate control system and the potential for unintended consequences led me to seek professional assistance. I would recommend consulting a workshop.

Thanks for the advice! Took it to the shop as you suggested. Turns out it was a corroded connector on the temp sensor, just like we suspected. 95€ later, and the AC is blasting cold air again. Appreciate the help!
