*Beats head on desk* Of course... I'll try it again pulling the cable but... That I have 12v available still pretty much indicates a bad clutch right?

If you are measuring the voltage on the pins without disconnecting the wire from the fan and IF the switch complete the circuit to ground (and I believe that is the case in the '85 190D), then there WILL be 12V on both pins except when the switch is closed. Then there will be 12+V on one pin and less than 1 V on the other. Marshall -- Marshall Booth Ph.D. Ass't Prof. (ret.)
