Does anyone have a circuit diagram for the AC fans on a W124 E280 1993 vintage. I have traced the wiring to a connector just behind the NS headlight. During the last warm spell and in traffic the temp. guage rose alarmingly. I traced out the circuit to the point that when I shorted the temp. switch on the thermostat housing and connected a 12v lamop to the aforementioned connector... it lit. However the fans do not operate at all under the same conditions. When I connected a meter to the fan side of the connector and spun the OS fan there was a discernable movement on the meter indicating that at least the wiring is intact. I may be making some blind assumptions here so I await correction and advice.
