Here's the specs that MB says should happen with a properly charged and operating A/C system for my car (C140).

The temp is set of "LO" (my car) and not recirculating inside air. Also used an external (accurate) temperature probe that was inserted into the center vent. The outside temp was close to 70F.

This data is from MB and this is what you should see at 40% and 80% RH (relative humidity). Also engine sb at 2000prm.

Outside ----- 40% RH---------80% RH
Temp -------A/C_Temp --- A/C_Temp
20-24----------5--------------------6-7
24-27----------6--------------------7-10
27-30----------6-8-----------------10-13

So for 21C (70F), you should see 5-6C (42 F) air coming out at RH of about 40 to 80%.
