Pishta, as I mentioned before, suspect an "in harness" spike diode. Carefully cut back the insulation and see if there's one in there and clip it out and check it. "Might be shorted."
Got it handled...took the old one out and the 2 wire harness was charred behind a metal bracket and was shorting to ground. Yard pull had good harness, bolted it in with old spacer, blamo! Cold air....Nice $18 bucks spent. still working.....
