Galloper outside temperature sensor issue

I'm having a frustrating issue with my 2003 Hyundai Galloper diesel. The outside temperature sensor seems faulty. I'm getting an error code, the AC won't turn on, my windshield washer spray nozzles are freezing even when it's not that cold, and the mirror heating isn't working. I'm thinking it might be a bad cable or plug connection to the sensor. Has anyone else experienced anything similar?

Whoa, that sounds like a mess! I had something similar happen with my Hyundai Santa Fe. Is the temperature reading on your dashboard completely off too? Mine was stuck at -40, which made everything go haywire.

Yeah, the temperature reading is totally off. It's showing something ridiculous like -30 degrees Celsius even when it's clearly above freezing. Did you manage to fix it yourself, or did you take it to a shop? Any idea what it cost you?

I ended up taking it to a workshop. Honestly, I'm not great with electrical stuff. They told me it was the sensor and a corroded connector. Best to get it checked by a professional.

Thanks for the advice! I took it to a local shop, and you were spot on! It was indeed the outside temperature sensor and a corroded connector. The whole repair cost me 95€. Everything's working perfectly now – AC, mirror heating, and no more frozen washer nozzles!
