Seat Ibiza Climate Control Panel Dead

I had a similar issue with my Seat Ibiza, although mine is a bit older. The air conditioning stopped working, and the heating was weak. Have you checked the electrical connectors going to the climate control panel and the blower motor? Those Ibizas are known for electronic faults and problems with the wiring harness. It could be a simple fix like cleaning or replacing a corroded connector. Also, have you checked the fuse for the blower motor?

Where exactly should I be looking for these electrical connectors? Is it something I can access myself, or will I need to take apart the dashboard?

The connectors are usually behind the center console. You might be able to reach them by removing the radio, but honestly, it's a bit fiddly. If you're not comfortable taking apart the dashboard, I'd recommend taking it to a workshop. It's probably a simple fix, and they should be able to diagnose it quickly. It was indeed a defective wiring harness in my case.

Took it to a local workshop, and they found a corroded electrical connector in the wiring harness, just like you said. They cleaned it, and the climate control panel works perfectly now. Total cost was 95€, so I am very happy. Thanks again for your help!
