Modus fog sensor issues

I'm having trouble with the fog sensor on my 2007 Renault Modus with a gasoline engine. The car has 151560 km on it. I'm getting an error, and the air conditioning won't switch on, the spray nozzles are frozen, and the mirror heating is dead. I suspect a dodgy cable or plug connection related to the fog sensor. Has anyone else experienced this?

I had something similar happen with my Modus. Same symptoms: AC dead, nozzles freezing, mirror heating kaput. Have you checked the wiring harness near the sensor? It's a common spot for corrosion and breaks.

Thanks for the quick reply! Do you remember exactly where on the wiring harness you found the issue? Any tips on getting to it without dismantling the dashboard? I'm trying to avoid a full exploratory surgery!

I can't recall the exact location, sorry. It was a while ago, and my mechanic sorted it. Given the symptoms, though, it's likely the fog sensor is the culprit. I'd suggest visiting a workshop. They should be able to diagnose and fix the defective cable or plug connection.

That's what I suspected. I was hoping to avoid it, but it sounds like a trip to the mechanic is unavoidable. I'll post the resolution. The repair cost was 95€.
