Captur climate control issues

Sounds like a power supply problem to the climate control unit. Have you checked the temperature sensor? A bad sensor can cause the whole system to shut down.

Could you tell me which temperature sensor to check and where it is?

I can't say exactly without diagnostics, but the internal temperature sensor on the dashboard is often the cause. Given your symptoms, I'd suggest a workshop. They found a faulty connection in the control panel wiring in my case, like you suspect. Cost me around 95€ and fixed everything.

Thanks, I'll take the Captur to a workshop for a wiring and connection inspection. Appreciate you sharing your experience and the cost!
