Wiring diagram interior heater c4 2010

[Morganbarne]

I bought my car 1,5 year ago with a defekt heater. I thought it was just to replace with a new.
But new heater. New resistance and tried a different display. Nothing works.
Something in the wires???
Do anyone have a wiring diagram?

Can you give more details about the car as they are needed to find the correct diagrams. We need year, engine, gearbox, body shape and if possible the RPO number from the Tyre pressure sticker on the door pillar. If you post the VIN as well, which will be obscured from public view, some members have access to the Stellantis system and may be able to help too.
