I have a new-to-me 1984 w123 wagon that has the euro/manual climate control configuration, i.e. A/C dial is on the upper panel and the larger lower switch panel has three dials and two sliding levers. I'm unfamiliar with these controls and haven't been able to find any instructions on how these work (like you would find in the original manual for the car). Does anyone here have a link to a thread or pdf of a manual that would explain these controls?
