Continuing the saga, after all that I had done thru this repair process I returned from business to find I had blown another fuse and was still not thrilled with my temp situation, after a message from Art Dalton I re-examined my relay diagram and realized that I had not placed them properly. I moved them, upon start up and further check I found my aux fans were indeed blowing the wrong way creating a very hot space where the radiator and AC condenser live. Pulled apart the nose of my car to find the harness I had replaced by my mechanic only to find that it was installed as it should be. After digesting this for a few hours I decided WTF I will snap the directional pin off this harness where it attaches behind the LF headlight and flip it over if it doesn't work he will get the car back anyway. Lo and behold the fans blow correctly and my temp situation is tremendous a constant 82-98 on the dash scale so far no blown fuses either. Wierd problem as when the car was at highway speed and enough air passed thru the radiator everything seemed fine. Lower speeds the temp went straight up, I think I blew relay fuses from the load of both fans working opposite each other. I will monitor that closely, I re-installed Jim Forgione's ch92http://pages.prodigy.net/jforgione/MB_S500.html and it now works the way it was supposed to keeping my car's temp down to very low levels even here on a 95F day with high humidity.
