Modus automatic temperature control issue

Alright, Renault Modus (2007, diesel) owners, I'm at my wit's end. My automatic temperature control has gone completely bonkers. It's like the car thinks it's always the same temperature inside. The air conditioning won't even kick on! I pulled the codes, and it's throwing a "faulty interior temperature sensor" error. Given the mileage (219951 km) I'm suspecting the sensor itself, but I’m also wondering if it might be a connection issue. Has anyone wrestled with this demon before?

Oh man, climate issues are the worst! I had a similar experience with my Modus, and it drove me nuts. Was the temperature reading completely off, or just fluctuating wildly? I mean, did it ever give you a remotely accurate reading, even for a little bit?

Good question! It's completely off. Stuck at a constant, unrealistic temperature. Never fluctuates, never even hints at being correct. Could you tell me if you had the same symptoms? Did you try to fix it yourself?

Yep, that's exactly what happened to mine, stuck temperature and all. Honestly, after poking around for a bit and getting nowhere, I bit the bullet and took it to a workshop. They said it was indeed the temperature sensor and a dodgy connection. Saved myself a bigger headache that way.

Right, that's the confirmation I needed. I was hoping to avoid the workshop, but I think you're right. My multimeter skills can only take me so far. I will take it to the shop. They quoted me around 95€, but I'm sure it will be worth it to have a functional climate control again. Thanks!
