I started troubleshooting my dead blower fan on my 87 300D. I checked the monovalve and then I went to check the Black aux circulating water pump, which is supposed to be on the pass side of the engine and which should follow the hoses that run of the radiator or water pump there..I traced everything out and and I found no Black aux circ water pump..

However I was blowing fuses like crazy for a while the last month on my blower fan, so I am guessing the blower fan is dead anyway, or else the blower regulator circuitry-- Is this a reasonable assumption? Has anyone has this occur? I am thinking several of u already have had this happen...
