Skoda Octavia: No Connection to Heater Control Unit

I have a Skoda Octavia Combi. The heating is not working, the error code cannot be read, and no connection can be established.

Yes, we always appreciate well-structured information. So, it looks like things are going to get cold in here now, huh?


Or do you have a question?

"Help yourself, and God will help you." I've been looking at the wiring diagram, and someone has removed a fuse. Now there's no power in the house; it's so cold that you have to open the windows (or maybe we need to turn something back on).

Thank you .
