Changing climate control interface?

So, actually what you want is to downgrade from Klimatronik to manual aircon.
Never seen one doing this, only upgrading, but I can tell you it does not work by just changing the panels. 100% not.
Ever read about IHKA, IHR, HR?
The downgrad panel is not able to handle that many stepper motors. Ever looked at the back of it with all connectors?

i personally hate a full auto hvac system so i am with you, the problem with a retrofit is if you can adapt the vent control cables to replace the servos it uses now, anything is possible it's just a matter of how many parts need to be replaced and if you can find a handy parts car in a junk yard, worst case would be you'd need to replace the whole hvac box and dash wiring harness
