[W126 Coupe] climate control problem ??

[Jay Hirsch]

Do not think the Euro climate control is compatible with US climate  
units and US units from 1985-91 for the S body cars are different  
than  on other models

Your 84 Euro car  is supposed to have  a simpler, better unit with  
less problems

If the plugs are the same, then the units should interchange
