Seat Ateca Climate Control Issues
Summary of the thread
A 2016 Seat Ateca with a diesel engine experienced a dead climate control panel, a fault indicating low heating output, and a non-functional air conditioning system. The suspected cause was an electronic fault, possibly a defective cable or plug connection. A similar issue was resolved by addressing a faulty electrical connector in the wiring harness related to the HVAC system. The problem was fixed by replacing the connector, restoring the climate control system's functionality.

Interesting. Where exactly should I be looking for these connectors and the wiring harness? Are they easily accessible, or will I need to remove parts of the dashboard?

Yes, it sounds like the same problem I encountered. I didn't attempt the repair myself; I took it to a workshop. They indicated the likely cause was a defective electrical connector in the wiring harness related to the HVAC system. Is it worth risking further damage by attempting a DIY fix?

Took it to the shop, and you were spot on. It was a faulty connector in the wiring harness for the climate control. They replaced the connector, and the HVAC system is now working perfectly. Total cost was 95€ Thanks again for your help!

I have a similar Seat Ateca. Did you check the electrical connectors to the climate control panel? I recall reading about issues with the wiring harness causing similar problems. Could that be the culprit?
