Okay, just checked with your connector-plan and it seems that I messed up the motors. Now suddenly everything makes sense. Datatek, thanks so much for your help here! Also many thanks to pwood and anyone else who spend some time to help me here!! Wishing you all the most beautiful weekend ever!

I had no idea that three is a connector layout section in rave - I'm learning, which is just great! Unfortunately I couldn't find the connector 253. But still great!!

Oh wow, that's a treasure for sure - thanks Datatek! On the photo of my plug, would you say port 1 is top left or bottom right?

Thank you so so much for your help pwood! But I'm afraid I still need some help. I found the attached diagram on Rave but I struggle on two points: - I have the following cable colors: white, brown, grey, black and red/black. Rave is talking about B,N,W,RB,S ??? - My plug looks like this...

I habe Nanocom Communication but no faults. Good point to check the inputs. Will do tomorrow!

Hey Datatek, that sounds like a plan. Merci!!

Hey Pwood, thanks for your reply. „New motors“ means they are realy new (Valeo). I don’t understand the relay thing. Nanocom doesn‘t see any faults. So, what exactly can I do?)

I need to change my hevac controller. Motors are new but book symbol stays on and distribution motor doesn‘t work. I have unit JFC102400. All I find is JFC102550. What do I have to convert to make this newer unit work?? Or does anybody have JVC102400 for sale? I‘m in Germany, so Europe would...
