Folks, I have a few problems with my 1987 300TD and I could really use some list wisdom tracking them down. The foremost, and the one I've forgotten about since the last warm days of last fall, is that my auxillary fan never comes on. On the way home from work last evening (outside temperature

Last night, with the key in the run position, I shorted the pins on the temperature sensor on thermostat housing and the fan came on as it should. (Didn't sound great, but it hasn't run in months either.) I did the same with the pins on the high pressure switch and again the fan ran as
