Fiat Petra Fog Sensor Issue

Hey, got a weird issue with my 2002 Fiat Petra, gasoline engine. Error memory says fog sensor problem. AC won't turn on, spray nozzles freeze up, and mirror heating's dead. Mileage is 213754 km. Any ideas?

A 2002 Fiat Petra is experiencing issues with the fog sensor, leading to problems with the AC, spray nozzles, and mirror heating. The problem is likely due to an electrical issue, possibly stemming from the fog sensor circuit. It is suggested to inspect the sensor's wiring harness and connector for damage or corrosion, typically located near the rearview mirror. Professional inspection at a workshop is recommended to accurately diagnose and resolve the issue.

That sounds like an electrical issue potentially stemming from the fog sensor circuit. Are you familiar with checking the sensor's wiring harness and connector for any signs of damage or corrosion?

Not really, where exactly is that located? And what should I look for?

The fog sensor is typically located near the rearview mirror, behind the plastic trim on the windshield. Given the multiple symptoms, it does suggest a cable or plug connection issue. Without specific diagnostic tools, it is difficult to pinpoint the exact fault. I would advise consulting a workshop for professional inspection.

Thanks, I'll take it to a shop. They reckon it's a defective connection and quoted 95€. Appreciate the help!
