Thanks for the information Jim,

I guess I picked a bad example for '95 owners but for the newer models ('96 and on), you can read the A/C operational parameters from the dash controller.
Press "REST" for 8 secs or until the display changes to "1" in the left window and "TEMP" in the right window.
Press left "AUTO" to advance to next step; press right "AUTO" to decrease one step.
Step #5 is evap temperature and #7 is compressor pressure in BAR. (14.7psi = 1 bar). So if you 'sort-of' remember the "Aux Fan Activation" tables, then you can tell by the pressure where the aux fans state should be.
Yesterday, I took a '02 E320 for a ride and pressed "REST"; sure enough the operational parameters read out. . it's a/c evap was 35F. . w/ the compressor at 15bar. 35F is . . . . cold!!
