Seat Toledo temperature sensor issue
Summary of the thread
A 2003 Seat Toledo with a gasoline engine is experiencing issues due to a fault with the outside temperature sensor, affecting the air conditioning, spray nozzles, and mirror heating. The likely cause is identified as a defective cable or plug connection to the sensor. The suggested solution is to inspect the wiring and connectors for loose connections or corrosion, and if unresolved, seek professional assistance. The problem was ultimately resolved by replacing the defective cable/plug connection at a workshop.

Yes, I checked the wiring as best as I could, but I didn't find anything obvious. You mentioned a loose connection or corrosion. Where exactly should I be looking? Is there a specific area that's prone to these issues? Any tips for sensor diagnostics?

Okay, so with my Astra, the problem was exactly as the mechanic suspected in your case: a corroded connector right at the sensor itself. It was a pain to see without proper light. Honestly, if you've already checked the easily accessible parts of the wiring, and sensor calibration doesn't solve it, I'd recommend taking it to a workshop. They'll have the right tools and experience to pinpoint the exact location of the fault. Could save you a lot of time and frustration!

Thank you for your support. I've followed your advice and took my Seat Toledo to the workshop. You were right; it was indeed a defective cable/plug connection. They replaced it for 95€, and now everything is working perfectly again!

Oh, I feel your pain! I had a similar issue with my old Opel Astra a few years back. The air conditioning wouldn't kick in, and I suspected the outside temperature sensor too. Have you checked the wiring and the connector to the vehicle temperature sensor? Maybe it's just a loose connection or corrosion.
