So, no Klima on Dan's model. The linked post below makes it appear that the MAS may control A/C functions. http://forums.mercedesclub.org.uk/showpost.php?p=126705&postcount=13
Post #4 here, says something different: http://mbworld.org/forums/190e-w201/48220-c-compressor-relay-92-190e-2-6-a.html Hmmm... if one of these relays is taking over some Klima functions, I wonder (shooting from the hip) if it works like the Klima does on my '85 W123… "if freon pressure is lost, a pressure switch tells the Klima to turn off the compressor solenoid, saving the compressor from damage." I know they changed the configuration and function of this thing many, many times but here's my schematic (all I can find)… maybe it'll jog a memory or point to a possibility until the real schematic appears. https://picasaweb.google.com/lh/photo/GMQYuBJUv3hTB_4vilWnuB_L548h0FhsE9Lwz-quTRM?feat=directlink Dave SoCal For completion, according to the manual the two other functions on a 1985 W123 Klima are: (1) when the engine is started, the relay keeps the compressor solenoid off until 10 seconds after the engine speed has reached 600 RPM. This "improves engine speed stabilization after startup." (2) with engine speed less than 1050 RPM, when the accelerator is floored, the compressor solenoid is released until the engine reaches 2150 RPM or the accelerator is released. This function is controlled by a microswitch on the valve cover. On Mar 14, 2012, at 6:22 PM, Jim Cathey wrote: > Compressor clutch coils can go bad, they're in a harsh > environment.
