I have W126 300sdl. It was converted to 134 before I got it. Car runs cool on the road(82-83) if I stop it climbs to 105. The auxilliary fan never helps out. If I jump the wires at the dryer the auxillary fan cuts on immediately. I take it the dryer switch is not sending a closed circuit signal ever.

Since I am in FL and can use the extra cooling, whats the drawback with just jumping that circuit at the dryer?

Will the 105 high speed circuit, if it is working(I havent seen it that hot to test) continue to work as designed also?

thanks for info
